Bernadette: So it's probably genetic.
Howard: Well, maybe. Mom also had just gotten some news that might have upset her.
Bernadette: What?
Howard: It's not important.
Bernadette: Come on, Howard, I'm going to be your wife. You can share anything with me.
Howard: You'd think that. But no.
Bernadette: You told her we were going to get married and she had a heart attack?
Howard: You can't take that personally.
Penny: How else is she supposed to take it?

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

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

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

Howard: Hell hound.
Raj: Who let the satanic dogs out?

Sheldon: Oh, what fresh hell is this?
Biosuit Nurse: Wait, you can't leave here, you've been exposed.
Sheldon: (Covering his face with his shirt) No, I haven't. It's all good.

Raj: Sheldon, that's my water.
Sheldon: Oh, dear Lord!
Leonard: That's not your water.
Raj: I know.
