Wil Wheaton: Hey, Stuart.
Stuart: I don't want to play anymore. It's too much pressure.
Wil Wheaton: Why, what happened?
Stuart: I've-I've said too much.
Wil Wheaton: You haven't said anything.
Stuart: Not to you, to them.
Wil Wheaton: Who's them?
Stuart: Ah! Now I have said too much!

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.

Wil Wheaton: All right, Professor Proton fans, get ready to meet Dr. Sheldon Cooper and Dr. Amy Farrah Fowler, a pair of real-life scientists who may win the Nobel Prize. That's like the Kids' Choice Award, but with more science and less slime.

Sheldon: Kids' Choice Award? Why would they let kids choose anything? They're basically human larvae.
Wil Wheaton: Well, they are kind of our target audience.
Sheldon: Greetings, children. Toys, am I right?
Amy: He is. He has hundreds of them.

Amy: Okay, imagine you're looking in a mirror. The image you see looks just like you. That's called symmetrical.
Sheldon: Now imagine you have a billion mirrors, and each of them reflects one thing about you correctly and a billion things about you incorrectly. And imagine the set of incorrect things are floating in an abstract n-dimensional hyperspace. Now imagine there was never a mirror to begin with.
