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!

Marissa: It's a little weird for us, too. I mean, instead of our baby looking like Zack, it's gonna look like Leonard.
Zack: Or Penny if it's a girl.
Penny: No, no, it's not gonna look- Sure.

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.

Zack: So listen, I got to be honest. We sort of have another reason for asking you here.
Marissa: We want to have a baby, but we can't do it on our own.
Zack: It could be because of the game me and my frat brothers used to play where we kicked each other in the balls over and over. But the doc says there's no telling.
Marissa: We just don't know.
Leonard: Huh. You went to college.

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.
