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!

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.

Leonard: Well, apparently, Zack sold his company for a ton of money and retired.
Sheldon: And that bothers you?
Leonard: I don't know. I mean I guess so. Yeah. It doesn't seem fair. I work hard.
I'm really smart. I've made substantial contributions to my field. But Zack gets to be rich, while I'm still working for a paycheck?
Sheldon: Well, a lot of people you don't know are rich. That doesn't seem to bother you. Mark Zuckerberg, Sultan of Brunei, Gordon Letwin.
Leonard: Who's that?
Sheldon: He's one of the first 11 employees of Microsoft.
Leonard: Yeah, well, I don't have to hang out with Gordon Letwin.
Sheldon: Well, that's too bad. He helped create the HPFS file system. Oh, the stories he could tell.

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.
