Raj: So I guess what's bugging me is that they only broke up 13 days ago, and now I'm dating her. So, am I, like, the good guy in my movie, or the bad guy in their movie?
Bernadette: Pretty sure you're the weird friend in our movie.

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.
