The Soup Nazi Season 7, Episode 6

Jerry

You can't eat this soup standing up, your knees buckle.

Elaine

Huh. All right. Come on.

Jerry

There's only one caveat -- the guy who runs the place is a little temperamental, especially about the ordering procedure. He's secretly referred to as the Soup Nazi.

Elaine

Why? What happens if you don't order right?

Jerry

He yells and you don't get your soup.
