    Sheldon worries about the approaching Christmas holidays and his indecision about what to buy for Penny, as he needs it to match the value of her gift to him. After deciding on a basket of bath items he discovers a large selection, so not knowing what Penny will get him, he buys the entire range to cover all contingencies. Penny's gift to Sheldon is a napkin both autographed and used by Leonard Nimoy. Sheldon, overwhelmed since he now possesses Nimoy's DNA and can grow his own Leonard Nimoy, gives Penny all the gift baskets and also a rare "Sheldon" hug.

    Meanwhile, Leonard meets visiting researcher and fellow experimental physicist Dr. David Underhill. Though Leonard envies David for being handsome and a more successful physicist than himself, he jumps at David's offer to help him in his research. Things come to a halt when David meets Penny and the two start dating - though they quickly break up when Penny discovers nude photos of his wife on his phone. Leonard only learns this when he comes to Penny's apartment to yell at her about their own on-off relationship. When he realizes his mistake, he and Penny cuddle each other to comfort each other.

    The gang spends Thanksgiving at Mrs. Wolowitz's house. As she is laid up in bed, Raj, Bernadette and Amy cook. Penny recalls her Thanksgiving in Las Vegas with her ex-boyfriend Zack, and a "fake" wedding. Her friends tell her the wedding was real, so she is legally married, causing tension between her and Leonard. Howard vainly tries to bond with his father-in-law, Mike, who instead starts to bond over football with Sheldon, who is apparently very knowledgeable as he was forced to watch the game with his father as a child.

    After Mike shares beers with Sheldon to comfort him because his father died while he was young, they continue to hit it off. Amy orders Sheldon to apologize to Howard after insulting him. A now-drunk Sheldon gestures to Amy, says to Mike, "Ain't she great?", and then swats her on the rear and suggests she get them more beers. Amy is shocked but delighted at the physical attention. Meanwhile, Penny has invited Zack over to sign the annulment papers to end their marriage (to the excitement of Raj, Bernadette, and Amy). Zack is at first reluctant to sign, expressing concern at how ending the marriage will affect their non-existent kids. Penny demands he sign, and he does. Mike finally compliments Howard, but then attributes his kindness to being drunk. Penny and Leonard reconcile.
