Raj: Bernie!
Bernadette: Oh, damn.
Stuart: Hey! What are the odds?
Bernadette: Yeah, seren-frickin'-dipity.

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!

Bernadette: One of the great things about being pregnant is drinking cranberry juice out of a wineglass and watching people freak out.

Penny: Is it possible that you're stressed because you're scared about getting married? I mean, it is a big change, and you're not good with little changes.
Sheldon: Well, that's nonsense. You name one little change I was upset with.
Penny: Uh, when they changed the green Skittle from lime to apple.
Sheldon: That is not the rainbow I grew up tasting.

Howard: It's a date. Just pick one.
Sheldon: It's not just a date, it's a textbook optimization problem. There is a perfect date. Just like there's a perfect room temperature and a perfect dessert.
Penny: Mm. There's no perfect dessert.
Sheldon: Yellow cake in the shape of a dinosaur with chocolate frosting, a scoop of vanilla ice cream on the side, not touching. You'll see. You'll have it at our wedding.
Amy: You wanna bet?
