Bernadette: That's pretty big talk for a man with a closet full of magic tricks at his mother's house.

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!

Amy: The only person who signed my yearbook was my mother. "Dear Amy, self respect and a hymen are far better than friends and fun. Love, mom."

Bernadette: Good Morning, handsome.
Howard: Good morning, mom.
Bernadette: It's me!

Amy: I have a sorta kinda boyfriend at home playing with a model train, but you don't hear me bitching about it.
