Penny: Uh-oh, somebody's still pouting.
Leonard: Leave me alone.
Penny: If it's because you lost a stick, I know where it went.

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?

Stuart: So what happened with you and Howard?
Raj: Says I was talking too much about dating Claire and Emily, and I accused him of being jealous.
Stuart: I'm jealous. Closest I've come to dating two women was that time I dated one woman.

Sheldon: I like a party as much as the next man, as long as the next man doesn't like a party.

Sheldon: I have a question about Batman. Batman is a man who dresses up like a bat. Man-bat is a part man, part bat hybrid. Now, if Man-Bat dressed up as a man to fight crime, would he be Man-Batman?
Leonard: No, he'd be Bat-Man-Bat.
Raj: But wouldn't Man-Batman just be a Batman that was bitten by a radioactive man?
Howard: But Batman is a man. You're talking about a man who would have the powers of a man. That's just Man-Man.
Sheldon: Well, isn't Man-Man just Man?
Leonard: But what if Man-Man dressed as a bat?
Raj: Well, that's just Batman.
Leonard: No, if a man dresses as a bat, that's Batman, but if Man-Man dresses as a bat, that's Batman-Man.
Howard: So does that answer your question?
Sheldon: Oh, I haven't asked it yet.
