Big Bang Theory Quote
Amy: I don't understand. What difference does it make if Leonard goes to Wil Wheaton's party?
Penny: Well. Wil Wheaton is Sheldon's mortal enemy.
Amy: Mortal enemy?
Penny: Mhm.
Amy: Sheldon, I knew you were a bit of a left-handed monkey wrench, but you really have a mortal enemy?
Sheldon: In fact, I have 61 of them. Would you like to see the list?
Penny: Oh, say no, say no, say no.
Sheldon: You just got off the list, would you like back on it?
