Big Bang Theory Quote
Penny: You know, for a smart guy, you really seem to have a hard time grasping the concept: "Don't piss off the people who handle the things you eat."
Amy: That does seem to be a valid principle.
Sheldon: I trust Penny will adhere to the official California Restaurant Workers' Solemn Oath of Ethics and Cleanliness.
Amy: I don't believe there's any such thing.
Sheldon: (Incredulous, to Leonard) You lied to me?
