Leonard: Wil's had lots of great guests. Jonathan Frakes, Brent Spiner, Michael Dorn, Gates McFadden.
Penny: Those are Star Trek people.
Leonard: Yes!
Penny: I only figured that out because I've never heard of any of them.
Wil Wheaton: I deserve that. I invited you on my show and I drove here.

Wil Wheaton: Game over, Moonpie.

Wil Wheaton: Did that guy just say "Revenge is a dish best served cold" to me in Klingon?

Wil Wheaton: Hey look, they named their team after me!

Wil Wheaton: You know that the movie actually has a little bit of a cult following.
Penny: Really?
Wil Wheaton: Yeah. I was at a science-fiction convention, and I saw a woman dressed as your half-ape character.
Leonard: Oh, if she was with an Indian guy dressed like a banana, that was just my friends, Howard and Raj.

Sheldon: It reminds me of when my stupid brother and sister would build forts in the living room, and wouldn't let me in. I hated that so much.
Amy: You know, there's nothing I can do about getting you invited to the symposium, but if you wanted we could build a fort.
Sheldon: Isn't that a little juvenile?
Amy: More juvenile than this? *Puts up picture of smiling Sheldon to her face*

Leonard: Well, you can spend the rest of the day being bitter about this--
Sheldon: Agreed.
Leonard: I was going to say "or," but why bother?
