Penny: And we ran into Zack.
Leonard: Oh. Yeah? How's he doing?
Penny: He got married.
Leonard: Oh. Well, that's nice.
Penny: Yeah, and he sold his company for a fortune and retired.
Leonard: Huh. And you ended up with me, so everybody wins.
Penny: Wait. You're not jealous of Zack, are you?
Leonard: What? Oh, absolutely not. In fact, he should be jealous of me because I have you. And a dungeon with over 30 rooms left unexplored because no one thought to search for secret doors under the wizard's throne.
Penny: Oh. You know, I'd like to go exploring.
Leonard: Really?
Penny: Mm-hmm.
Leonard: Well, I'll get the dice back out.

Leonard: What would you be if you were attached to another object by an inclined plane, wrapped helically around an axis?
Sheldon: Screwed?
Leonard: There you go.

Sheldon: This song is never going to stop. Have you ever dealt with something so relentlessly irritating?
Leonard: That's a trick question, right?

Leonard: Penny, as a scientist, my job is to figure out why things happen. But I don't think I'll ever understand how someone like me could get to be with someone like you. You know maybe I don't need to understand it, I just need to be grateful. I love you, Penny.

Bernadette: This is so great. Why don't we do it more often?
Amy: Because you have two kids, I have Sheldon, and Penny's apparently in the gym all the time, 'cause damn, look at her!
Bernadette: Yeah, so impressive how you manage to bounce back after having no babies.
Penny: Ah, another reason why we don't do this more often.

Penny: Thank you, but you shouldn't have spent so much.
Zack: Nah. It's cool. I sold my company for a boatload of money. And then I bought a boat. Then I got married. Guess where.
Amy: On your boat?
Zack: No, but that would've been awesome!

Penny: Did-did you send this over?
Zack: I did. I asked for the most expensive one they have. They said it was $200, and I said I want a more expensive one. And then, they said it was $300.
Amy: But it-it was the same-
Penny: Don't.
