Bernadette: It's okay, I'm just being emotional about this. Can you not tell Howard?
Stuart: Well, don't you think it'd be healthier if you told him what's going on with you?
Bernadette: Don't you think it'd be healthier if you had your own apartment, grown man?
Stuart: Your secret is safe with me.

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!

Penny: Hey, since when do you do laundry on a Thursday?
Sheldon: Oh, I had an accident at work, I slipped and fell on my soup sack.
Penny: You know, there was a time I would say "What's a soup sack?" But I'm glad we're past that.

Penny: You know, there was a time I would say "God bless you," and then you would say "If you must invoke an imaginary deity, how about Thor?" And I would say, "How do you know I didn't mean Thor?" And then you would say "Touche," and that there ends the tale of why I no longer say "God bless you."
Sheldon: Well, we have had some fun, haven't we?
Penny: Oh, yeah.

Stuart: Oh, thanks again for letting me use your laptop last night.
Bernadette: No problem.
Stuart: Was just doing my taxes.
Bernadette: Okay.
Stuart: Actually, if I could if I could just check one more-
Bernadette: Already cleared the browser history.
Stuart: You're a good woman.
