Today marks the fifteenth anniversary of Seinfeld’s final episode. Though the characters famously worked under a “no changing” policy, one thing often changed throughout the series’ nine seasons: Kramer’s career goals. While the steady source of his rent and diner money was a mystery (he remained on strike from his job at H&H Bagels for virtually the show’s entirety), he had myriad short-term gigs and get-rich-quick schemes, some of which even paid off; he did make $18,000 betting on a horse race and, most notably, was able to retire (from what?) when his Coffee Table Book of Coffee Tables got optioned for a movie. Below, we take a look at Kramer’s entire work history, from miniscule odd jobs to outlandish schemes.
