Bernadette: I don't want to drive that. It's such a mom car.
Howard: The guy at the dealership said they're not just for moms anymore.
Raj: Then again, he did think you were my husband.
Bernadette: They thought it at the ultrasound. Why not at the car dealership?

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!

Sheldon: Stuart, wait. I do know what it feels like to be left out.
Bert: I know how it feels, too.
Sheldon: All right, this is about me and him; you're not part of it.

Amy: There's nothing to be afraid of, Sheldon.
Sheldon: The average cork speed is 25 miles per hour. If that is too fast around a school, it is certainly too fast around a kitchen.
Amy: Been 15 minutes. Just sayin'.
Sheldon: Okay, I can do this. Just give me a moment. (Cork pops and Sheldon shrieks) Oh! Mimosas coming up.

Penny: Hey, have you ever heard of the Van Nuys Comic-Con?
Leonard: Yeah, it's a dinky little convention where they sell collectibles and get sad D-list celebrities to appear. Why?
Penny: I got asked to sign autographs there.
Leonard: That's awesome! Is this for Serial Ape-ist?
Penny: Well, it could be for the monkey movie. It could be my hemorrhoid commercial. The list does not go on.
