(Sheldon appears with all the gift baskets)
Penny: Sheldon! All I need is a healthy ovum and I can grow my own Leonard Nimoy! And Penny, what a surprise. And we suck at it. Buy a basket! Come on in. David: Really. David: So, you and her? David: Yeah, why not? He couldn't even get it started. He miniaturizes himself, enters the city where he loses his superpowers. He's a very handsome man. I've been offering to show you around for a year and a half. Leonard Nimoy. Leonard opens the door to Penny. Leonard: Come on, it's Christmas, just give me this one. Leonard: It's David Underhill. Leonard: Since when? Leonard: Since when? Now, Raj. Oh, a napkin. Penny. Penny: Because a smart guy takes the nude photos of his wife off his cell phone before he tries to take nude photos of his girlfriend. Penny: Okay, you know what? Penny: Why are you yelling at me? Scene: Penny's apartment. Sheldon: I possess the DNA of Leonard Nimoy?! Sheldon: To Sheldon, live long and prosper. Then I'll look up the price of her gift online, choose the basket closest to that value, give it to her and then I'll return the others for a full refund.

Summary: 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 realises his mistake, he and Penny cuddle each other to comfort each other. Meanwhile, 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.
