Stuart: Is it just me or has no one been in the store for hours?
Denise: Yeah, it is weirdly quiet. [gasps] Nobody's in the street.
Stuart: Huh. Well, that's strange.
Denise: You thinking what I'm thinking?
Stuart: They cut that meteorite open and unleashed a space plague?
Denise: Exactly.

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.
Stuart: Of course it is. It's a little wrong to say a tomato is a vegetable, it's very wrong to say it's a suspension bridge.

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.
Bernadette: Sorry, did I startle you?
Stuart: Yes, but at this point pretty much any customer does.

Stuart: Whoa, whoa. You're not gonna cut open a meteor, are you? Have you not learned anything from comic books? Space viruses? Pod people? I sell nothing but warnings.

Howard: And then Andy said if we want privacy, we should plant some trees. The only way I know how to do that is to give a dollar and tree shows up in Israel.

Bert: I don't really have dreams, when I sleep or in life.
