Bernadette: (To Sheldon) Brush your teeth and go to bed!

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!

Leonard: Penny, I told you if you don't put him in his crate at night, he just runs around the apartment.

Raj: Okay, just to be clear, roller skating was my idea, and I'm very unhappy that you turned it into a double date. I hope you both fall on your asses and break your coccyxes.
Sheldon: The plural of coccyx is coccyges.
Raj: Screw you. Give me back my lima beans.

Penny: What happened?
Leonard: Sheldon's escaped and he's terrorizing the village.
