Plot

Tension arises when a magazine fails to mention Leonard in an article about the paper he co-wrote with Sheldon, and a blackout at Mrs. Wolowitz's home leads to a final family dinner in her honor.

After interviewing Sheldon, Scientific American writes a glowing article about Leonard and Sheldon's latest theory without mentioning Leonard by name, only referring to him as "Dr. Cooper's team". Leonard ends up being upset but not mad at the situation until Sheldon, trying to make things right in his own eyes, finds out what caused the error. Meanwhile, Raj offers to help Howard, Bernadette and Stuart clean out Howard's mother's house, Stuart who Howard is letting stay there a little while longer. Just as Howard, Bernadette and Raj get to the house, Stuart tells them the power has been out since the middle of the night. What Howard ends up being upset about is that the food in the freezer - the last food Debbie ever cooked - has thawed and thus cannot be refrozen and thus saved. As there is enough to feed an army, Howard invites all their friends over for one last meal courtesy of Mrs. Wolowitz. Debbie's spirit pervades the meal in more ways than one, courtesy of Leonard and Sheldon's feud and Bernadette's resulting action.—Huggo

As Sheldon checks out his mail box, he finishes reciting the irrational constant pi to one thousand places. Sheldon gets his Scientific American magazine which has an article on the theory that Leonard proposed and Sheldon helped develop, but the article only mentions "Dr. Cooper and his team" having worked on it. Leonard is not identified. Amy tells Sheldon that Leonard is going to be very upset.

Raj and Howard head over to his mother's house to go through her things. He finds it hard sorting through everything. A lot of his mother's stuff brings back fond memories though Bernadette wonders about the drawer full of catsup packets.

Sheldon tries to tell Leonard about the omission of his name in the article with the example that Leonard's name is not on the cable TV bill. Sheldon mentions the article and Leonard thinks that they hated it. The article did praise their work, but didn't mention Leonard. Sheldon tries to help lose his anger by giving him a massage which Leonard doesn't want. "Cooper and his team?" exclaims Leonard. Leonard says that the bright side is that they are talking about the theory. Sheldon agrees that that is what is important like when Stan Lee and Steve Ditko created Spider-Man and only Stan Lee is ever mentioned, gets all the money, is in the all the movies, etc. Leonard is very unhappy.

At his mother's house, Stuart is still living there. Stuart tells Howard that the power is going to be out until the next day. After ask how long after the power out, Howard runs to check the freezer and finds the food defrosting. Howard is upset because it is the last food his mother ever made and they can't refreeze it. He wants them to eat it, though there is twenty pounds of food. To use up all the food, Howard decides to invite everyone over for a meal. It will be like his mother is feeding them one last time.

In Penny's place, Leonard is still depressed over his name being excluded. Penny wonders who even reads Scientific American especially with no celebrity on the cover. She is going to cheer him up by going online to shop for him. Leonard says that that is her cheering up thing until she finds a helicopter with a camera making him feel better. Sheldon comes in after talking to the author of the article who has been following his work for years and only did the article because Sheldon's name was connected with it. Also they made an editorial decision to only list the lead author. Also Howard called to invite them over for dinner.

On the way to the Wolowitz house, both Sheldon and Leonard are complaining to their girls about the magazine article. Amy tells Sheldon that is was Leonard's idea; however, Sheldon has ideas all the time. i.e. Reverse SeaWorld where dolphins pet people. Was it his fault that he has a bigger reputation or that his name came first? Then he asked if it was his fault that he didn't correct the author and Amy starts looking the pretty bird off to her left. Leonard is upset that Sheldon is willing to let everyone think that he did all the work.

In the kitchen, Raj, Bernadette and Howard start to prepare their meal. He finds strange things in the freezer like cake from his Bar Mitzvah and his prom boutonniere. The meal consists of three briskets, four meatloaf, Jewish ravioli (noodle strudel), two pound cakes, a tub of matzo ball soup and no vegetables. His mother thought she could cure any sickness with her cooking including the time Howard got food poisoning from it. A distraught Howard then laments that he'll never get to talk to his mother again, bringing a compassionate Bernadette to give him a comforting hug and ask him if he wants to call off the dinner. Howard declines, saying he wants to go ahead with the dinner.

Stuart escorts the guys into the living room lit by candles and menorahs. Penny thinks everything looks beautiful. Sheldon comes in, says hello and then "Hello, Leonard" who has to be mentioned by name. Howard tells everyone that this is not a sad occasion and that they are going to have the kind of dinner they have had so many times before including the heartburn. The girls tell the guys to behave themselves which they agree to.

At the table, the food is found to be delicious even though there are not vegetables. Howard corrects them that he has tomatoes in the packets of catsup. Amy feels like they are in an 18th-century French salon due to the candle lighting. Sheldon describe to Penny that the French salon is where intellectuals talk about the issues of the day. Penny compares it to The View. Amy tells Sheldon what "The View" is, which Sheldon is aware of. Whoopi Goldberg is on it as she was on Star Trek: The Next Generation. The topic of female equality among super heroes comes up, since in the revamped Marvel universe, Thor (mispronounced Tor) is going to be a woman. Amy quips that there won't be equality until Thor is a mother and the others are fine with her pumping out breast milk at work. Leonard complains that Sheldon would prefer execution over inspiration like with their paper. Howard favors execution since he is an engineer bringing concepts to reality. Sheldon agrees; however, Leonard notes that Sheldon always tears down Howard and engineering as a profession. Penny wants them to stop because if she wanted to hear curse words, she would go to her real hair salon. Sheldon and Leonard really start to fight, with Leonard even threatening to throw his food at Sheldon. Bernadette stops things before they can escalate before she gets angry and demands that Sheldon and Leonard go into the living room. She is heard yelling at the top of her voice that Howard is dealing with the loss of his mother. Howard wants to know if they think that she sounds like his mother. Everyone says that they never noticed.

Finally everyone is overstuffed and lying around the living room. Penny doesn't think she ever ate that much food in her entire life. Sheldon finds out that the research paper was mentioned in Physics Today and that Leonard was credited. An unenthusiastic "yay" is heard. Bernadette comes down the steps saying that she found more Tums for their upset stomachs and a more enthusiastic "yay" is heard.
