Over the course of its 180 episodes, Seinfeldsometimes went to some pretty weird places for comedy. Some of its darkest episodes, like “The Limo,” in which George (Jason Alexander) unwittingly poses as a famous white supremacist, and “The Opera,” which sees the return of “Crazy” Joe Davola, were written by the same man, Larry Charles. Charles also penned the Season 5 episode, “The Bris,” which covers everything from suicide, the ethics of circumcision, and one of Seinfeld’s most bizarre plot lines, Kramer’s (Michael Richards) discovery of the so-called pig-man. While visiting friends who recently had a baby, Kramer accidentally barges into the wrong hospital room and is horrified to find what he refers to as a “pig man.” As recently revealed by Charles in his memoir Comedy Samurai: Forty Years of Blood, Guts and Laughter, the pig-man was actually inspired by the 1973 British satirical drama O Lucky Man! starring Malcolm McDowell.
