Bernadette: What's wrong with his face?
Howard: A lot of people have been asking that. He's smiling.
Bernadette: Hey, Stuart, you look pretty happy.
Stuart: Oh, yeah. I, uh, asked Denise out on a date, and she said yes.
Bernadette: Aw. That's great. But don't smile like that in front of Halley. She just started sleeping through the night.

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!

Stuart: Do you still want to go out with me?
Denise: Absolutely. Hey, maybe we can go find Nemo together.
Stuart: That's a good one.
Denise: Do your 63 other crayon friends know you're out?
Stuart: Are you just gonna make fun of me all night?
Denise: Probably.
Stuart: Great. So what are we thinking, Chinese?
Denise: Yeah, I'm in the mood for orange chicken.

Amy: Well, Leonard and Penny are our best friends. They know us better than anyone. They said it's the perfect gift. We must be missing something. You don't think it's a marital aid, do you?
Sheldon: Don't be silly. Amy, how is this big glass shaft going to aid our marriage?

Amy: Let's just go to sleep. We'll look at it in the morning with fresh eyes, and maybe it'll come to us.
Sheldon: Fine.
Amy: Or we go tear apart that box and look for a clue.
Sheldon: Staying up past my bedtime and solving mysteries? Who knew married life could be this good?
