Bernadette: We were out one night, and things got a little spontaneous.
Amy: Oh, that sounds juicy.
Bernadette: Well, Sheldon was going on and on about time zones and railroad schedules, and I went out-
Penny: Wait, I remember that. Hang on. You did it at our place?
Bernadette: Kind of on Sheldon's bed.
Amy: What?!
Penny: No!
Bernadette: I was headed to the bathroom, and I passed Howie on his way out. Usually he says, "Do not go in there," but this time he said, "Hey, let's go in here."

Bernadette: I had a plan. I kept leaving Dove bar wrappers around to explain any weight gain.
Amy: Where did you get empty Dove bar wrappers?
Bernadette: From all the Dove bars I ate! I'm pregnant! Try to keep up!

Stuart: Oh, so she's good enough for Howard but not for me?
Howard: Yeah.
Bernadette: Yeah. Go have weird relationships with your own mother and cousin. This is his turf.

Leonard: You don't go into science for the money.
Bernadette: Speak for yourself. Last month my company both invented and cured restless eye syndrome. Ka-ching, ya blinky chumps!

Penny: Oh, it's Leonard. He says Sheldon's drunk and they're gonna do karaoke if we want to join them.
Penny: That sounds fun.
Amy: Oh, no. Sheldon's drunk texting me.
Bernadette: What's it say?
Amy: "Would you like to sing karaoke with us."
Bernadette: How is that a drunk text?
Amy: He used a period instead of a question mark. He's so wasted.

Howard: I love you. And I'm not just saying that because your breasts are gonna get bigger.

Sheldon: You're kidding! What kind of maniacs have coitus in someone else's bedroom?!
Howard: Thank you, Pasadena! Good night!
