Kramer, Kramer, Kramer
At one point, Kramer somehow starts working at a company without actually being hired. He just decides one day that he works there. He also, in classic Cosmo fashion, manages to get fired within three days. However, during those three days, Jerry and Kramer fall into a typical couple trope with Jerry getting mad at Kramer for working long hours.

You can argue that Jerry is eccentric, George is a weird goose, and Elaine definitely has her fair share of craziness, but not one character on the show (well, maybe spare Crazy Joe Devola) is nearly as strange as Kramer. His lifestyle is absolutely ridiculous, and it remains a mystery how he’s able to rent a New York City apartment for over ten years with no job.
