Big Bang Theory Quote
Sheldon: (Opens Penny's gift) Oh, a napkin...
Penny: Turn it over.
Sheldon: (Reading) "To Sheldon Live long and prosper... Leonard Nimoy!"
Penny: He came into the restaurant. Sorry the napkin's dirty - he wiped his mouth with it.
Sheldon: (Face twitching excitedly) I possess the DNA of Leonard Nimoy?
Penny: Yeah, yeah, I guess, but look, he signed it.
Sheldon: (Now shaking with excitement) Do you realize what this means? All I need is a healthy ovum and I could grow my own Leonard Nimoy!
Penny: Okay, all I'm giving you is the napkin, Sheldon.
