Big Bang Theory Quote
Amy: Sheldon. Your fight's with Leonard. Penny's got nothing to do...
Sheldon: Careful Amy. The friend of my enemy's girlfriend is my enemy.
Amy: Really?
Sheldon: Yes. You're either with me or against me.
Amy: You want to take the bus to work?
Sheldon: Maybe there's a third option.
