Penny: Hey, guys! My friends and I got tired of dancing so we came over to have sex with you.
(The guys continue to play Halo).
Penny: Told ya.
(Penny and her friends leave).
Sheldon: Why did you hit pause?
Leonard: I thought I heard something.
Rajesh: What?
Leonard: No, never mind.

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

Raj: [to Amy] If you were having Sheldon's baby, would you really want him in the room?
Penny: Yeah, if he's in the room when they're making the baby, I'll give you $10.

Penny: I mean, who even reads Scientific American?
Leonard: It's kind of a big deal.
Penny: If it's such a big deal, how come the biggest celebrity they could get for the cover is a molecule?

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.

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

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