Leonard Hofstadter and Sheldon Cooper are both brilliant physicists working at Cal Tech in Pasadena, California. They are colleagues, best friends, and roommates, although in all capacities their relationship is always tested primarily by Sheldon's regimented, deeply eccentric, and non-conventional ways. They are also friends with their Cal Tech colleagues mechanical engineer Howard Wolowitz and astrophysicist Rajesh Koothrappali. The foursome spend their time working on their individual work projects, playing video games, watching science-fiction movies, or reading comic books. As they are self-professed nerds, all have little or no luck with women. When Penny, a pretty woman and an aspiring actress from Omaha, moves into the apartment across the hall from Leonard and Sheldon's, Leonard has another aspiration in life, namely to get Penny to be his girlfriend.

Did You Know?


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 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. See more »


Sheldon's trademark knock (3 knocks + name, 3 knocks + name, 3 knocks + name) was not established until later in the first season, however, in a scene that pre-dates the start of the show, he is shown doing that knock sequence. See more »


Sheldon: You're not done with her, are you?
Leonard Hofstadter: Our babies are gonna be smart and beautiful.
Sheldon: Not to mention imaginary.

Guilty Pleasure
16 October 2007 | by (Canada) – See all my reviews

This show is definitely one of my guilty pleasures! Tuesdays are spent anxiously awaiting its posting on iTunes so I can download it, as I live in Canada & don't have cable. TBBT is a trip down memory lane for me, as it IS my high school experience (20+ years ago, I was a smarter Penny). I love the characters, especially Leonard who is adorable, and the smarmy yet surprisingly charming Wolowitz. It has the feel of "Frasier Goes To College". I do agree though that they should lose the laugh track - annoying, but not enough to make me stop watching. BTW, very smart of CBS to originally have offered the pilot as a free download or I would never have given it a look. Now I'm an addict!
