Treehouse of Horror XVI/References

Trivia

 * The episode is very similar to the Buffy the Vampire Slayer episode "Halloween", in which most of the residents of Sunnydale don cursed costumes that transform them into what they are dressed as. It is also similar to the classic Twilight Zone episode The Masks in which four greedy heirs are turned into monsters by the hideous masks each wears at their benefactor's behest, Halloweentown, and The Fairly OddParents Halloween special ("Scary GodParents") in which Timmy wishes that everybody's Halloween costumes were real. The episode is also similar to an issue of the Simpson Comic Bartman, in which an Itchy and Scratchy brought to life through alien technology create a nuclear explosion which turns the Simpsons into costumed superheroes.
