Bernadette: He told you all this at the planetarium?
Raj: No, no, we went to House of Pies. He got banana cream. I got coconut. We did halfsies.
Howard: You did pie halfsies with another man?
Bernadette: You mean other than you?
Howard: Yeah.

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: No, the campus isn't safe at night. There's raccoons and undergrads just walking around like they own the place.

Raj: Uh, you know, my secret to making great omelets is that I beat the egg whites separately. Speaking of which, how long have you been separated? Speaking of which, how long have you been separated?
Nell: About two weeks.
Raj: That is not a lot of weeks. In fact, that's the bare minimum to get to the plural "weeks".

Howard: Look at this cute picture of Halley in the bath.
Leonard: Aw, that's great.
Howard: Want me to send it to you?
Leonard: No, on your phone it's cute, on my phone it's a crime.
