Cosmo Kramer is one of the most recognizable Seinfeld characters and is often seen carrying out crazy schemes in his apartment. But not even Kramer can put an end to maritime oil spills all by himself. Despite never holding a real job, Kramer has a wide network of friends, partners, and associate who appear in his apartment over the 9 season series.
So which character appears the most in Kramer’s apartment? Is it Jerry’s arch nemesis Newman, who is often a co-conspirator in Kramer’s half-baked plans? Or perhaps it’s Jerry, who always leaves the door open for Kramer and may be looking to reciprocate? Maybe it’s Elaine, who “pops in” to Jerry’s apartment and always seems to get pulled into Kramer’s cyclone of outlandish behavior? Or is it George, who is always hanging out at Jerry’s and shares Kramer’s affection for cooking up a ruse?
