Trivia

Raj's inability to talk to women except when consuming alcohol, is based on an old co-worker of Executive Producer Bill Prady, when he worked at a computer company.

The cast members learned to play their instruments for the show. (Amy plays the harp, Sheldon plays the theremin and recorder, and Leonard plays the cello). In addition, Howard is a professional piano player.
Most of the time, Leonard has no lenses in his glasses.
Mayim Bialik is the only cast member to have a PhD. In 2008, she completed her Neuroscience studies. She earned her PhD in Neuroscience.
Jim Parsons' audition for the role of Dr. Sheldon Cooper was so good, that Creator Chuck Lorre immediately asked him to come in for a second one, because Lorre wanted to be one hundred percent sure Parsons was as brilliant as he seemed. After the second audition went perfectly, Lorre cast him on the spot.
The two main characters (Sheldon Cooper and Leonard Hofstadter) are named after late television Producer Sheldon Leonard.
When Sheldon plays the theremin (which is widely regarded as one of the hardest instruments to play), that is actually Jim Parsons playing it.
During the third season, the producers became aware of a series called "The Theorists," produced and broadcast in the country of Belarus, that was a virtual copy of this show. Legal action over copyright infringement would have been futile, since the production company was pretty much owned by the Belarus government. However, a lawsuit turned out not to be necessary, because when word got out that the show was a rip-off, the actors and actresses quit, and the show was immediately cancelled.
On January 14, 2011, CBS gave the series a rare vote of confidence when it issued a three-year renewal through the 2013-14 season. It then received another three-season renewal on March 12, 2014, meaning the show will run at least twelve seasons. This marked the first time in modern television history a scripted television series received back-to-back three-season renewals.
During a first season episode Raj, Leonard, and Howard are trying to find a fourth person to replace Sheldon on their physics bowl team. Raj suggests Mayim Bialik, saying, "You know who's apparently very smart, is the girl who played TV's Blossom (1990). She got a PhD. in neuroscience or something." Leonard responds, "Raj, we're not getting TV's Blossom to join our physics bowl team." During season three, Bialik started playing the regular role of Dr. Amy Farrah-Fowler on the show. Dr. Fowler has a PhD. like Dr. Bialik, in Neurobiology, a.k.a. Neuroscience.
Kaley Cuoco missed filming two episodes of season three, because of a broken leg, that was the result of a horseback riding accident. In her first appearance following the accident, she was filmed standing behind a counter.
Sheldon's soothing song, "Soft Kitty", is based on an Australian children's song from Executive Producer Bill Prady's daughter's pre school. The song has been featured on Australian children's television show Play School (1966).
Even though Jim Parsons' character Sheldon Cooper is a huge Star Trek (1966) fan, Parsons himself has never seen the show. The same is true for Doctor Who (1963).
On January 3, 2013, a team of Brazilian biologists announced their name for a newly-discovered species of orchid bee: Euglossa bazinga. This was to honor the show, and specifically Sheldon's mocking catchphrase "bazinga". Long mistaken for another bee, Euglossa ignita, the new species was deliberately tagged "bazinga" for its history of fooling entomologists. Executive Producer Steven Molaro responded in a press release: "We are always extremely flattered when the science community embraces our show. Sheldon would be honored to know that Euglossa bazinga was inspired by him. In fact, after Mothra (1961) and griffins, bees are his third-favorite flying creature."
In fall 2010 Kaley Cuoco revealed to CBS's Watch! Magazine's Behind the Scenes (2008) that she and her co-star and love interest Johnny Galecki had secretly dated for two years earlier in the run of the show, but they were no longer together.
Penny has been using the same purse since season one, episode two.
Despite the fact that some viewers take Sheldon's behavior, mannerisms, and social skills as a sign that he has Asperger's syndrome, or otherwise falls on the autism spectrum, the producers have persistently denied in many interviews that Sheldon has Asperger's or any other type of autism. It should be noted, however, that Jim Parsons (Sheldon) has stated that he does think that Sheldon actually does have Asperger's syndrome, and portrays him as such.
Sheldon can be seen wearing various versions of "Flash" t-shirts throughout the series. In the series The Flash (2014), character Cisco Ramon frequently wears "The Big Bang Theory"-based shirts, such as one with Sheldon's catchphrase "Bazinga!"
Although Sheldon does not drive, Jim Parsons gets motion sickness from riding in cars, and prefers to drive them.
Sheldon frequently wears t-shirts with the characters or symbols of the Green Lantern, the Flash, or the old television show The Greatest American Hero (1981). The shirts from the "Green Lantern" comic book series are various colors with a corresponding symbol, with each color representing a different corps of heroes or villains (Red Lanterns, Orange Lanterns, et cetera). In the comics, each color also represents an emotion, thus possibly giving the viewer a clue to Sheldon's temperament for the day.
Each of the male characters has a signature clothing article that is worn in virtually every episode: Sheldon, t-shirts worn over long-sleeve shirts; Leonard, hoodies worn over a t-shirt and under a jacket; Raj, sweater-vest worn over a shirt, and usually under some type of outerwear; Howard, dickie worn under some type of outerwear. Howard usually has a pin on the left side of his dickie of the head of a space alien, and he wears large belt buckles.
On five episodes or more of season six, Mayim Bialik's right hand was hidden in certain ways and camera shots to conceal the the injury she received, and the glove she wore to cover it, from an automobile accident in August of 2012.
Floors two, three and four of Sheldon and Leonard's apartment building are the same set just re-dressed for each scene. This can be seen in the fact that the scuff marks on the molding are identical on each level as they walk up the stairs.
Sara Gilbert (Leslie) who plays a former girlfriend of Leonard's, also played Johnny Galecki's girlfriend in Roseanne (1988). Laurie Metcalf, who plays Sheldon's mother, was also his co-star in Roseanne (1988) and Sara Gilbert's aunt.
Jim Parsons as Sheldon Cooper wears numerous shirts containing the number 73, this is also the year Jim was born in real life 1973, and Cooper repeatedly states that 73 is his favorite number.
Kevin Sussman, who plays Stuart Bloom the comic book store owner, actually worked in a comic book store before becoming an actor.
Both Raj's and Bernadette and Howard's apartment are filmed on the same set, and are just completely redecorated to change scene, this is why it is rare to see both apartments in one episode.
Sheldon didn't always have his door-knocking quirk. In season one, episode five, "The Hamburger Postulate", he knocks on Penny's door without knocking and calling her three times.
The full names and occupations of the characters are as follows: Dr. Leonard Leakey Hofstader, Ph.D., Experimental Physicist; Dr. Sheldon Lee Cooper, B.S., M.S., M.A., Ph.D., Sc.D., Theoretical Physicist; Howard Joel Wolowitz, M.Eng, Aerospace Engineer; Dr. Rajesh Ramayan Koothrappali, Ph.D., Astrophysics; Dr. Bernadette Mary Ann Rostenkowski Wolowitz, Ph.D., Microbiology; and Dr. Amy Farrah Fowler, Ph.D., Neurobiology. Penny's last name has yet to be revealed.
Out of the main male cast members, Howard is the only one who hasn't seen Penny naked in person, despite being the first to flirt with her.
Kaley Cuoco presented the Best Performance by an Actor in a television series, musical or comedy at the 2011 Golden Globe Awards to her co-star Jim Parsons.
With the exception of the pilot, every show name follows the same format as the show's title, that being the name of a scientific episode or theory.
As the series progressed, each taping of the show was attended by Caltech students.
Johnny Galecki was originally approached to play Sheldon, but felt that he would be better fit to play the role of Leonard.
Sheldon is from Texas, as is Jim Parsons.
Howard's house also appeared in Everybody Loves Raymond (1996).
Bernadette did not originally have such a high pitched voice. When she first appeared, she had a rather normal pitch voice and as her character began to take shape, she adopted the quirky high pitched voice which Melissa Rauch says she based off her mother's voice "without the Jersey".
The theme song uses the line "Autotrophs began to drool." This is a science joke. The word "autotroph" means "self-nourishing" and refers to life-forms (plants and algae) that create their own food internally and don't need to eat.
One of Johnny Galecki's early roles was in an episode of Blossom (1990) in which he played Mayim Bialik's love interest who takes her to a "make-out party".
The quick response (QR) code, which is visible in Stewart's comic book store, contains a link to the website for the comic book center of Pasadena.
The opening cast shot always features the series' regulars enjoying dinner together. The opening cast credits cast shot in seasons two through four, for instance, depict Howard, Raj, Leonard, Penny, and Sheldon on what appears to be pizza night. However, Leonard is seen holding a plate with a white meat, and some type of vegetable, such as asparagus spears. This is apparently a reference to his lactose intolerance, which would make him averse to pizza (unless he ordered it without cheese). Amy and Bernadette were added to the shot starting in season six, even though both had been regulars on the show since season four.
Penny was an add-on from a different sitcom concept. She had been originally envisioned as Katie, a more cynical, hard-drinking, streetwise girl who worked at a make-up salon. In the original unaired pilot, she was played by Amanda Walsh.
During his appearance on Inside the Actors Studio (1994), Jim Parsons revealed his three favorite scenes: Sheldon receiving a gift from Penny - a napkin signed and used by Leonard Nimoy, Sheldon presenting Amy the relationship agreement, and Sheldon drinking Long Island Iced Tea for the first time.
In the early episodes of season one, Sheldon has two character traits that were not established right away. First, he understood the nature of romantic and sexual relationships. In the first few episodes, he chides Leonard for his hopes of getting into a relationship with Penny, often telling Leonard that he has no chance of having sex with her. Also, Sheldon understood the nature of sarcasm, as he occasionally used it himself in the early episodes. Later, his character evolved into a purely intellectual person and an emotional "man-child", who does not fully understand sex, love, or sarcasm. Second, in the early episodes, Sheldon did not use his three-times knock (knock-knock-knock "Penny", et cetera) that has become one of the character's now well known idiosyncrasies that did not begin until midway through season one.
Bob Newhart agreed to appear in the show on one condition, that he have a recurring role. Newhart appeared in four episodes as Arthur "Professor Proton" Jeffries.
The original working title of the show was "Lenny, Penny, and Kenny".
The equations written on the boards in various episodes that Leonard and Sheldon are working on, are real physics equations and are verified as accurate by consulting physicists.
All of the figurines and posters in Howard's room (and later on in his house with Bernadette) are female superheroes or science fiction characters. The one non-female figurine, Jabba the Hutt, has Princess Leia (in her slave girl costume) sitting in front. Later on in the series, they accumulate a figurine of Bernadette after the episode where he and Raj got a 3-D printer.
The character Howard Wolowitz is named after someone the creator worked with at a computer company.
Wil Wheaton's house number (1701) is the same as the hull number of the U.S.S. Enterprise on Star Trek: The Next Generation (1987) (NCC 1701-D).
In the original unaired pilot, the theme song of the show was "She Blinded Me with Science" by Thomas Dolby. Later on, however, a short MIDI rendition of the song is used as Howard's ringtone in The Big Bang Theory: The Lizard-Spock Expansion (2008).
Jim Parsons (Sheldon) and Kaley Cuocuo (Penny) are the world's highest paid television actor and actress, with earnings of twenty-nine million dollars and twenty-eight and a half million dollars, having made that income from June 1, 2014 to June 1, 2015. (Forbes 2015)
According to numerous entertainment reports, CBS has reported a large jump in the series' ratings for season six, and has attributed the increased audience to the exposure of the show in re-runs on TBS, which airs the series three nights a week in prime-time blocks of up to three hours.
Leonard's last name, Hofstadter, refers to two well-known scientists: Robert Hofstadter, the 1961 Nobel Laureate in Physics, and his son Douglas R. Hofstadter, who researched consciousness and cognition, and whose best-selling book about philosophy, mathematics, puzzles, art, and music, "Gödel, Escher, Bach: An Eternal Golden Braid", was published in 1979, and won him the 1980 Pulitzer Prize for general non-fiction.
Barry Kripke (John Ross Bowie) has exactly the same speech impediment as cartoon character Elmer Fudd, also a Warner Brothers character.
While a guest on the National Public Radio program "Talk of the Nation", Mayim Bialik confirmed that the university, at which the characters attend and/or teach, is based on the California Institute of Technology (Caltech) in Pasadena. Additionally, in one episode, the character of Leonard stated that he worked at Caltech.
Raj says that Spock had a date every seven years. He is referring to Pon Farr, the Vulcan mating cycle that occurs every seven years. Vulcans must mate in the time of Pon Farr, otherwise they will die, so Spock has a mandatory hook-up every seven years.
Sheldon's apartment flag that is on the refrigerator is supposed to be turned upside down only if the apartment is in distress, however, it is seen upside down in several episodes.
As avid comic book fans, the guys frequently talk about comic book characters, or are wearing t-shirts or other paraphernalia of comics. They frequently mention DC Comics characters such as Superman, Batman, Green Lantern, the Flash, and Wonder Woman. DC Comics and this show are owned and produced by subsidiaries of Time Warner, Inc.
In tribute to Carol Ann Susi, who played Howard's mom, who recently passed, a small picture of her is on the side of Sheldon and Leonard's fridge. It is a small square that can be seen in episodes after her death. The picture is so small that it cannot be recognized. However, in the behind the scenes DVD feature, it is mentioned that it is her.
The mother of Aarti Mann, who plays the role of Raj's sister Priya, is an obstetrician and gynecologist. In the show, Raj often states that his (and Priya's) father is a gynecologist.
One of the shows that survived the 2007 and 2008 writers strike. The show started in 2007, and the strike started in late 2007. This resulted in season one only being seventeen episodes.
While much of the show has focused on String Theory, the most often mentioned physicist is Hawking. However, the "Father of String Theory" is Dr. Leonard Susskind, who has proven Hawking wrong on several occasions.
Amy's apartment number "314" is a reference to pi, which is usually rounded off to 3.14.
Sheldon has invented a time of day called "pre-evening". In Turkish, there's a time of day called "aksamustu", which basically means "pre-evening". In Bengali, there is a time called "godhuli", which also means "pre-evening". In Czech, there is a time of day called "podvecer", which also means "pre-evening".
Leonard is the only regular male character who wears glasses. His on-again/off-again girlfriend Penny is the only regular female character who doesn't wear glasses.
Sheldon verbally reveals his and Leonard's Pasadena apartment 4A's location as being 2311 Los Robles in season four, episode five, "The Desperation Emanation". In the one hundredth episode, Sheldon also reveals that their apartment building is across the street from the Colorado Avenue Chevron gas station, making their building a corner location, on the corner of Los Robles and Colorado. There are two incidences of this intersection in southern California, both located in Los Angeles County, the first one is E. Colorado Boulevard and N. Los Robles Avenue, Pasadena, California, 91101, and the second one is Colorado Boulevard and Los Robles Street, Los Angeles, California, 90041. However, 2311 Los Robles is not an address by either one of those intersections. Leonard does reveal, however, that they live in Pasadena, while declaring himself the Darth Vader of Pasadena.
No two bumpers are exactly alike. Bumpers are those short videos used to separate scenes in the show.
Howard's mother was almost never seen, only heard, despite often being as close as the next room. Conversely, via Skype, Raj's parents are quite often seen, despite being across the world in India, except when his father visited Pasadena.
Sheldon only swears three times, in the first season, the fourth season, and again in the fifth season. Other times, he is shown to use either substitute words or only say the first letter.
In one of the episodes, Raj and Leonard run into Nathan Fillion. They greet him and tell him they are big fans of Firefly (2001) and Dr. Horrible's Sing-Along Blog (2008). Simon Helberg (Howard) played the character "Moist" in Dr. Horrible's.
Some of the signs in the laundry room read "No open containers on the machines", "Do not leave laundry unattended", and "Please keep your clothes on while doing laundry".
In early episodes of season one, Sheldon mentions having an older brother, in addition to his twin sister, Missy. In one instance, he mentions being bullied by this older brother. However, while Missy has been seen on the show, the brother was never mentioned again, even when his mother visits. She only mentions Missy. He was mentioned in season three episode four, as well. In later seasons, Sheldon's brother was mentioned in season seven episode eleven, season eight episode twenty, season eight episode twenty-three, and season nine episode five.
The names Sheldon, Leonard, Cooper, and Hofstadter all appear on the list of Nobel Laureates in Physics. Furthermore, Sheldon and Cooper are names of physicists who won the prize for theory, and Leonard and Hofstadter are names of those who won for experiment.
Leonard's middle name is Leakey. Leakey is the name of a renowned family in the fields of archaeology, anthropology, and paleontology. Louis Leakey (1903-72) was a British archaeologist and naturalist, whose critical work helped to establish human evolutionary development in Africa. He also created or co-created several organizations for future research and for protecting wildlife in Africa. He also helped to establish a tradition of palaeoanthropological inquiry, and was able to motivate the next generation to continue, especially within his own family. Mary Leakey (1913-96), his wife, was a British archaeologist and anthropologist who discovered many firsts. For much of her career, she worked together with her husband in Kenya's Olduvai Gorge, uncovering relics of ancient hominines. She also developed a system of classifying the relics they found. After Louis' death, she became a leading palaeoanthropologist, helping to further establish the Leakey name and tradition with the training of her son, Richard Leakey.
In the German-dubbed version, the voice actor for Sheldon Cooper is the same person who usually dubs Leonardo DiCaprio.
In every one of the main female characters' first appearances on the show, the first person to speak to them are their future mates. In the pilot, when Penny is introduced, the first person to speak to her is Leonard, in season three, episode five, "The Creepy Candy Coating Corollary", when Bernadette is introduced, the first person to speak to her is Howard, and in season three, episode twenty-three, "The Lunar Excitation", when Amy is introduced, the first person to speak to her is Sheldon.
Melissa Rauch, who plays the role of Bernadette, a Catholic, in the series, is Jewish in real-life.
Leonard wouldn't eat dairy (lactose intolerent) or drink wine (sulphates) at the start of the show. Now he drinks wine all the time.
Writer Chuck Lorre leaves a small insert called a "vanity card" at the very end of each episode. If you pause it at the end, you can read it.
In the same scene that Raj says that "Blossom" would be a great addition to the Physics Bowl team, he also mentions that the "girl from The Wonder Years" was also smart. In a later episode, Danica McKeller (who played Winnie on The Wonder Years (1988)) plays a character who makes out with Raj.
While having lunch at the University canteen, or other eating scenes, characters don't actually eat most of the time. Howard only pretends to eat the food by moving his mouth like he is chewing it, Sheldon and Leonard just play with their food with fork. Amy and Penny are sometimes shown eating food. They only talk most of the time.
Amy is allergic to avocados, as revealed in season eight.
Leonard is the only male lead character who hasn't taken his pants off while under the influence: Raj took his off at the coffee shop while under the influence of an experimental personality altering drug, Howard took his off on the international space station after his teammates gave him a shot for his anxiety, and Sheldon took his off on stage while accepting an award in science after Penny gives him multiple glasses of wine.
In an unaired pilot episode, instead of Raj and Howard, Leonard and Sheldon had a female companion named Gilda, who had a big crush on Leonard.
Banned from China because of its "offensive content".
From June 2015 to June 2016, cast members Jim Parsons, Johnny Galecki, Simon Helberg, and Kunal Nayyar were the top four highest paid television actors, and actress Kaley Cuoco was the highest paid actress for the same time period.
When Chuck Lorre first pitched the show to the studios, he intended for it be an adult version of the show as seen today. In the hopes of attracting as many male viewers as possible, he wrote the show with an all female cast. The female characters associated with the male main characters reflect the original characters' personas: Sheldon was originally Missy (a tall, attractive brunette from Texas, who lacked intelligence), and lived with an older woman named Beverly (an intelligent scientist from New Jersey, who took advantage of her roommate. Penny lived, as she does now, across the hall, but originally had an Indian roommate named Priya (a lawyer from New Delhi). It could be assumed that characters like Bernadette and Amy might have been potential characters to add later, as well as a single male love interest in the form of unintelligent Zack.
The first season references the show "Blossom", and the actress that got a neuroscience degree. This was before they hired the actual actress to be Amy.
In season five, episode nineteen, "The Weekend Vortex", for some reason, Kaley Cuoco is omitted from the credits, dispite appearing in the episode. In the beginning of the episode, while Leonard, Howard, and Raj are walking up the stairs, the credits start with "Starring Johnny Galecki, Jim Parsons, Simon Helberg, Kunal Nayyar..." instead of "Starring Johnny Galecki, Jim Parsons, Kaley Cuoco, Simon Helberg, Kunal Nayyar..."
Sheldon once mentioned he views himself and Howard to be acquaintances in the third season. In reality, Parsons and Helberg are good friends with each other.
While Wil Wheaton was appearing on the show, he took a photo of the set's coffee table and posted it on his much-followed blog. Among the materials on the coffee table, were copies of "Mental Floss Magazine"; "The Sandman Vol. 6: Fables and Reflections" by Neil Gaiman; a package of Pepperidge Farm Sausalito milk chocolate macadamia nut chunk cookies; a package of Red Vines; and a package of Tim's brand original-flavor lightly salted potato chips.
Sheldon's routine knocking ritual was done by Penny in season two, before Sheldon did it on the same episode.
In one Halloween episode, Amy and Sheldon are brainstorming couples-themed costumes, in which to dress up. Sheldon has a list of their suggestions written on a whiteboard, and while his half of the board has various genre characters listed, Amy's half has mostly romantic couples. The only exception is a listing that reads "Blossom and Joey", a reference to the title character Mayim Bialik portrayed in Blossom (1990), and that character's brother.
Howard's mother's name is Debbie Wolowitz.
Sometimes in the second or third floor of Sheldon and Leonard's apartment building, the caution tape on the broken elevator will come undone. Sheldon will sometimes stop and fix the tape.
In season one, episode seven, "The Dumpling Paradox", when Leonard talks about cutting Raj in half to play Halo, Raj speaks with Penny in the room. If you look at the table, you will notice that Raj does not have an alcoholic drink.
It is both stated and implied, in several episodes, that Leonard's character does not snore, but later there is an entire episode dedicated to him snoring, and the resulting surgery.
Sheldon's father's name is George.
The characters often mention how Raj cannot talk to women "unless he's drunk", but in fact, he only needs one sip to lose his inhibitions, as evident in many of the episodes.
In season six, episode ten, "The Fish Guts Replacement", Sheldon reveals that his favorite cartoon theme song is Teenage Mutant Ninja Turtles..."turtle power!" The infectious 90's anthem was written by none other than Big Bang Theory show runner and writer Chuck Lorre.
Sheldon and Leonard are atheists, yet the scientific theory that is the basis for their careers (and the show's title) "The Big Bang Theory" was actually proposed and developed by a Catholic priest, Father Georges Lemaître.
Simon Helberg's father guest starred on M*A*S*H (1972), in season eleven, episode eight, "The Moon is Not Blue". He played Corporal Bannister, who is plagued with panic attacks whenever he is around women. Hawkeye and B.J. give him pills for confidence without telling him they are placebos. The pills work, and he becomes a ladies' man. This is the same as Raj, but he remedies it with alcohol.

In season four, Penny is going out with Zack, and they attend a costume party at the comic book store, where he goes as Superman, and she goes as Wonder Woman. Kaley Cuoco briefly dated Henry Cavill, who portrays Superman in Man of Steel (2013), Batman v Superman: Dawn of Justice (2016), and the upcoming Justice League movies.
Penny (Kaley Cuoco) has never had her maiden name disclosed on-screen before. An interview with one of the writer's of the show revealed that the writer's of the show are aware of this, and due to superstitious reasons, are intent on not revealing it ever on-camera.

Amy wears a knee length skirt with dark or colorful tights, a long sleeve, collared blouse with a knitted sleeveless cardigan, often underneath a long sleeved cardigan. Bernadette wears a mid-thigh length, usually floral, dress with dark or colored tights, and a short sleeved button up cardigan. Penny is the only main character whose clothes do not follow a pattern.

The UK's Channel Four and E4 appear to have slightly edited dialogue from certain episodes as the audience laughter abruptly starts, stops, or jumps, suggesting bad "cut and shunt" editing, not consistent with the professional editing standards Warner Brothers Television usually releases. This is result of UK Broadcast Standards compliance edits made, as the two channels show the program multiple times across daytime, afternoon, evening, and nighttime slots.

Spoilers 

The trivia items below may give away important plot points.

Penny is the only remaining main character whose surname has yet to be revealed. While her maiden name is still unrevealed, in the season nine premiere, she took Leonard's surname of Hofsteader.
In the one hundredth episode, where Leonard asks Penny out again, Penny is wearing the same shirt she wore in the pilot. This was probably to represent Leonard falling in love again with the same girl he did one hundred episodes before.
Howard's mother's voice was heard throughout the show, but her face has never been actually seen on-screen (she appeared very briefly on-screen in the season five finale, as the camera pans up from the rooftop, but her face was still never shown). She died after the actress who played her, Carol Ann Susi, died of cancer.
Chuck Lorre stated in an interview that Penny's surname is Barrington, the reason is yet to be revealed.
Carol Ann Susi, who plays Howard's unseen mother, died from cancer on November 11, 2014. Her character was subsequently written out of the show.
Penny's surname has never been revealed on the show. That is, until she married Leonard, and her new last name is Hoffsteder.
The cast and crew have performed two "flash mobs" to audiences after taping an episode, one to Carly Rae Jepsen's "Call Me Maybe", and the other to Mark Ronson's "Uptown Funk".
Raj, Priya, Leonard, and Bernadette are the only characters to have had both of their parents introduced in the series, prior to the season ten episode aired on Monday September 19, at 8 p.m. Eastern and 7 p.m. Central. In this episode, both of Penny's parents were introduced together.
Of all of the main characters, Leonard and Penny have had the same amount of relationships over the course of the show (Penny: Kurt, Zack, Stuart, Mike, and of course Leonard) (Leonard: Penny, Dr. Elizabeth, Priya, Leslie, and Stephanie), then Raj (Lucy and Emily), Bernadette (Glenn and Howard), and Howard (Leslie and Bernadette). Amy (Dave and Sheldon) and Sheldon (Amy).
In the season five finale, when Howard and Bernadette are getting married, during the wedding, Raj talks without drinking any alcohol, even though there is Amy, Penny, and Bernadette in the same place.
Most of the characters have evolved since their first appearance. Sheldon: He gains more feelings about women, and ever gets physical with Amy, and tells her he loves her. Howard: He is less creepy then he was in the first season, and finally settled down. Raj: He can now speak to women without being drunk. Amy: She is less like Sheldon, and not as robotic.
In season six, episode two, "The Decoupling Fluctuation", Amy mentions that she and Sheldon will be getting married in exactly four years. At the end of the season ten finale, Sheldon proposes to Amy, making this to be a somewhat valid prediction.
