Bernadette: That was really impressive.
Penny: Damn right it was impressive.
Bernadette: Okay, that tone doesn't work with me.

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.

Sheldon: Oh, but don't worry. I won't do that to you.
Amy: Maybe you should.
Sheldon: What?
Amy: This has been your lifelong dream. And you may not get another chance. I don't want to be the reason that you don't win a Nobel.
Sheldon: You're the only reason I deserve one.

Bernadette: Look at Howard. He was a disaster when I met him. Now he's a foxy astronaut with a hot wife.
Raj: Wait, he always wanted to be an astronaut.
Bernadette: He thinks that, too. That's how good I am.

Penny: No, it's not that.
Bernadette: Then why?
Penny: Honestly, I don't know if I'm up to it. You know, the last project I managed was my high school yearbook.
Bernadette: And?
Penny: And that was the year we didn't have one. - And? And that was the year we didn't have one. Apparently, the printers won't make them without getting paid.
Bernadette: What happened to the money?
Penny: Uh, if I didn't know then, I'm not going to magically know now.
