Big Bang Theory Quote
Penny: I think I know how you did the card trick.
Sheldon: Oh, please. If I don't know, you don't know; that's axiomatic.
Penny: Come here.
(Penny whispers in Howard's ear)
Howard: You're right.
Penny: (seeing Sheldon's indignation) Not too bad for someone who doesn't know what "axiomatic" means.
