Sheldon: What do you want, Howard?
Howard: We were just calling to see if you'd heard yet.
Sheldon: We haven't.
Amy: But thank you for getting up so early to call. That was very thoughtful.
Bernadette: Oh, please. We have two little kids. We've been up for an hour.

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!

Amy: Oh. That's me. Hello? Yes, this is Dr. Fowler. I see. Okay, thank you. We won.
Penny: Congratulations!
Leonard: Oh, my God!
Sheldon: We did it.
Amy: I know. Can you believe it?
Sheldon: That's a good point. What if I'm dreaming? [Leonard slaps Sheldon] We won the Nobel Prize!

Sheldon: It's happening! [phone chimes] Unknown caller. It's got to be them.
Amy: Okay, put it on speaker.
Sheldon: Hello?
Amy: Hi.
Barry Kripke: Hello. This is Sweden calling. Is this Dr. Cooper and Dr. Fowler?
Sheldon: Yes.
Amy: Yeah.
Barry Kripke: Congratulations. It is my pleasure to inform you that you've won the Nobel Prize in being suckers!

Penny: So, I guess the only thing that actually stays the same is that things are always changing.
Sheldon: Interesting. So you're saying the inevitability of change might be a universal constant.
Penny: Well, there's a little more to it than that, but, yeah, sure.
