Michael Jackson guest-starred in the 'Stark Raving Dad' episode of The Simpsons, playing a psychiatric patient who claimed to be Michael Jackson but clearly was not, being tall and white and bald :
Jackson pitched several story ideas for the episode, including Bart telling everyone in town that Michael Jackson was coming to his house.
He also requested several script changes, including that he wanted to have a scene in which he and Bart wrote a song.
Jackson especially liked Bart and wanted to give him a number one single, so he wrote much of the song "Do the Bartman" although he did not receive credit for it.
Jackson also wrote the song "Happy Birthday Lisa" for the episode....
