Big Bang Theory Quote
Penny: I think I'll pass, but you guys enjoy your extra 21 seconds.
Leonard: I bet if I could make you understand why this is such a cool thing, we'd still be together.
Penny: Hmm... yeah, no we wouldn't.
(Raj whispers something to Howard)
Howard: Uh-huh. I'm guessing 21 seconds had something to do with that, too.
