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.
