Big Bang Theory Quote
Sheldon: I really think we should examine the chain of causality here.
Leonard: Must we?
Sheldon: Event A: A beautiful woman stands naked in our shower. Event B: We drive halfway across town to retrieve a television set from the aforementioned woman's ex-boyfriend. Query: On what plane of existence is there even a semi-rational link between these events?
Leonard: She asked me to do her a favor, Sheldon.
Sheldon: Ah, yes. Well, that may be the proximal cause of our journey, but we both know it only exists in contradistinction to the higher-level distal cause.
Leonard: Which is?
Sheldon: You think with your penis.
