Gracie Films is the production company behind The Simpsons, and its theater logo normally ends episodes with a woman shushing the audience. For the annual Treehouse of Horror Halloween specials, which began in 1990, that familiar ending was given horror-themed variations. This version swaps the shush for a scream, making the logo itself part of the spooky joke. Clips of the variant later circulated on soundboards and in fan edits, where its instant recognizability and short length keep it popular for Halloween posts and surprise endings.
