Or more simply, the five fingers are the optimal evolutionary shape that the creature here desires towards.In the episode Simpson and Delilah, Homer befriends his new secretary Karl (played by actor Harvey Fierstein voiced).
However, because Fierstein thought that Karl was not a reasonable representative of the gay community, he refused to let the producer use his image as an idea to sketch the character. Michael Jackson used to be a guest in the episode Stark Raving Dad. In it he played a fictional version of himself.
Strangely, Michael refused to enter his own name at the end of the film, instead he took the alias John Jay Smith.
