Stuart: If you still want to hang out as friends, I'd like that.
Ruchi: Thanks, Stuart. I'd like that, too.
Stuart: And the fungus is under the toenail.

Stuart: Oh, Sheldon, I'm afraid you couldn't be more wrong.
Sheldon: More wrong? Wrong is an absolute state and not subject to gradation.

Howard: Hang on, I know a place where you could you stay and earn some money at the same time.
Stuart: Great!
Howard: I just have to warn you: it will involve humiliation, degradation and verbal abuse.
Stuart: So, what's the catch?

Bernadette: Hey, Stuart.
Stuart: *startled* Hey.

Sheldon: Well, that's nonsense. You name one little change I was upset with.
Penny: Uh, when they changed the green Skittle from lime to apple.
Sheldon: That is not the rainbow I grew up tasting.

Sheldon: Why can't there just be one week each month for famous people to die?
Amy: Well, they've already arranged to die in threes. What more do you want from them?
