Penny: Morning, Sheldon! Come dance with me!

Sheldon: …No.

Penny: Why not?

Sheldon: Penny, while I subscribe to the ‘Many Worlds’ theory, which posits the existence of infinite number of Sheldons in an infinite number of universes, I assure you that in none of them am I dancing.

Penny: Are you fun in any of them?

Sheldon: The math would suggest that in a few I’m a clown made of candy. But I don’t dance.
