The Simpsons: 10 Hidden Jokes Everybody Missed
7. Lisa Outs The Celebrity Cameos
Bart didn't get to see the Itchy & Scratchy movie when it was first released during season four, but a hyperactive Lisa gave him the lowdown on what he missed when she arrived home from the movie theatre.
During her overzealous description of the "greatest movie [she's] ever seen", Lisa mentions two celebs who cameoed in the film: Dustin Hoffman and Michael Jackson. They didn't use their real names "but you could tell it was them", she explains.
This a shrewd reference to two previous Simpsons cameos by the same stars, who voiced characters in the show under pseudonyms. Jackson was credited as John Jay Smith and Hoffman as Sam Etic.
The Simpsons was contractually obliged to keep those cameos under wraps, but the writers found a clever way to spill the beans.
