Sheldon: Oh good Penny, you're here to exchange gifts! You'll be pleased to know I'm prepared for whatever you have to offer.
Penny: Okay. Here.
Sheldon: I should note I'm having some digestive distress, so If I excuse myself abruptly don't be alarmed. [opens gift] Oh, a napkin.
Penny: Turn it over.
Sheldon: [reaches for chair, reading from napkin] To Sheldon, live long and prosper, Leonard Nimoy.
Penny: Yea he came into the restaurant. Sorry that napkin's dirty, he wiped his mouth with it.
Sheldon: [freaking out] I possess the DNA of Leonard Nimoy?!
Penny: Well, yea I guess but look he signed it!
Sheldon: Do you realize what this means? All I need is a healthy ovum and I can grow my own Leonard Nimoy!
Penny: Okay, all I'm giving you is the napkin Sheldon.
Sheldon: Be right back.

[Sheldon comes out with many gift baskets]
Penny: Sheldon! What did you do!
Sheldon: I know! It's not enough is it. Here. [tentatively reaches out to hug her]
Penny: Leonard look, Sheldon's hugging me!
Leonard: It's a Saturnalia miracle!
