Big Bang Theory Quote
Leonard: Oh, no!
(Star Wars' Darth Vader theme is playing)
Penny: What is that?
Leonard: That is Sheldon's "I'm unhappy and about to destroy the planet" music. Hey, let's just go to your place.
Penny: Well, wait, if he's unhappy shouldn't we talk to him?
Leonard: Shouldn't we talk to him? Have you learned nothing in six years?
