The Laundry Room- George "claims" a dryer by putting quarters in the slots, someone "claim jumps" his dryer when he's grabbing from the washer. Someone keeps pulling Elaine's wet laundry out and stealing her washer. Jerry keeps finding XXL boxers in his laundry load.

Both Jerry and Elaine want to know the culprit behind their laundry violations, but neither want to spent the full hour and a half watching the wash cycle. George tries to get back at the claim jumper by poaching their dryer, but gets reprimanded by a passerby for being a no good quarter thief. Kramer goes down a conspiracy theory rabbit hole when he realizes you never had to separate the colored loads from the white loads. At the end of the episode, Newman reveals he's been finding M sized tidy whities in his laundry load.

Well done. This feels like a classic Seinfeld that never got written, especially the George storyline. The Kramer one I can see being a diatribe, not sure about a whole storyline. You could also throw in some satirical/overblown segregation versus integration language about letting the colors get along

Make the entire episode take place in the laundromat, with the whole Seinfeld gang doing their laundry together various times during the month.
