Plot summary
Elaine needs Kramer to stand guard over an antique armoire she bought off the sidewalk, but Kramer is powerless to stop street toughs from hauling it away. George looks down on Jerry and his girlfriend's excessive displays of smooching and baby talk, and gets motivated to mock them to their face by mimicking them with Susan. Jerry values the staggeringly good soups served by the "Soup Nazi" so much that he will enforce the Soup Nazi's draconian rules at everyone else's expense. Elaine presumptuously flouts the Soup Nazi's rules, starting a spiteful feud.
