Penny: Wait. Wait, Sheldon come back, you forgot something.
Sheldon: What?
Penny: This plasma grenade. Ha! Look, it's raining you!

Sheldon: Woman, you are playing with forces beyond your ken.
Penny: Yeah, well your Ken can kiss my Barbie.

Leonard: If I take it off, Sheldon wins.
Penny: Sweetie, every night you don't kill him in his sleep, he wins.

Leonard: What am I supposed to do?
Penny: Err, keep your mouth off other women.

Leonard: Well, the only way we can play teams at this point is if we cut Raj in half.
Raj: Oh, sure, cut the foreigner in half. There's a billion more where he came from.

Leonard: Wow, Penny, you're on fire!
Penny: Yeah, so is Sheldon!

Penny: She'll have sex with anyone as long as they keep buying her things.
Howard: Really?
Penny: Yeah!
Howard: Yay! If you'll excuse me, I have some bar mitzvah bonds to cash.
