Soup Nazi (Season 7, Episode 6)
The “Soup Nazi” is one of the most unforgettable characters in television history. He was only in the show for one episode (not including the brutal finale), but he made a lasting impression.
The peak of this episode is when Elaine goes into his store thinking that she will get soup with no problem, not believing in what Kramer, Jerry and George have told her. This leads to Elaine getting tossed from the shop with the famous line “no soup for you,” which he also uses on George earlier in the episode when he asks for bread.
