John F. Kennedy Jr. was the son of former President of the United States, John F. Kennedy. Kennedy was seen alongside his father as a resident of Hell during the song, "Christmas Time in Hell", in "Mr. Hankey's Christmas Classics". The episode aired just six months after Kennedy's death.
Kennedy appeared with a photo-realistic head, much like Saddam Hussein. He wore a purple, long-sleeve shirt with "Boston" printed slightly above its center.
