"The Puerto Rican Day" - Seinfeld
It's pretty obvious as to why this episode was pulled just by looking at the title. In the episode, George, Elaine, Kramer, and Jerry get stuck in traffic during a Puerto Rican Day parade. The episode was riddled with negative stereotypes against Puerto Ricans and even showed someone burning a Puerto Rican flag. The PR community was not pleased with how they were portrayed. The episode was cut from syndication.
