Diablo is a magician at Magic Palace.
When the Simpson family was at the restaurant, Diablo had his show there. Marge, little bit dazed from drinking too much Long Island iced tea, offered herself as a volunteer for his next illusion. She was talking too much, so he put a ball gag to her mouth and gave her to four consecutive guillotines. When the blades fell, Marge disappeared in a flash. Four monkeys, wearing similar dress to Marge, jumped out of the baskets of the guillotine. Marge herself appeared in a giant banana peel. The audience applauded, but then monkeys started playing with Marge. Diablo had to help her because it wasn't part of the act.
