Big Bang Theory Quote
Penny: Hey, Sheldon. What's going on?
Sheldon: I need your opinion on a matter of semiotics.
Penny: I'm sorry?
Sheldon: Semiotics, the study of signs and symbols. It's a branch of philosophy related to linguistics.
Penny: Okay, sweetie, I know you think you're explaining yourself, but you're really not.
