Quote from George in The Finale
D.A. Hoyt: State your name. Soup Nazi: Yev Kassem. D.A. Hoyt: Could you spell that? Soup Nazi: No, next question. D.A. Hoyt: How do you know the defendants? Soup Nazi: They used to come to my restaurant. [flashback to George and Jerry ordering soup. After George raises the fact he didn't get any bread, he is banned from the store by The Soup Nazi.]
