The writer of the creepypasta confronts Matt Groening about a lost episode that everybody affiliated with the show refuses to acknowledge. Groening gives him a website address and begs him never to speak about the episode again.
When the writer visits the website he finds nothing but a download link, which contains the lost episode. In the episode Bart breaks the window on a plane and is sucked out. After his death, his family apparently sit at their kitchen table and cry for an entire year, before going to visit his grave. At the cemetery, Bart's corpse is laying on top of his grave and all the other graves bear the names of The Simpsons guest stars, even those who had not appeared on the show at the time the episode would have been written.
Has a sequel written by the same author, known as "A Dead Bart Update".
Dead Bart has proven to be fairly influential, helping spawn the "lost episode" genre of creepypasta.
The Story contains examples of:
- Adult Fear: A family loses a young member in a horrific accident, and the others cross the Despair Event Horizon as a result.
- Art Shift: The drawing of Bart's body is described as "photo realistic".
- Death Fic: The whole premise of the creepypasta is about a lost episode of The Simpsons concerning Bart Simpson's death.
- Despair Event Horizon: The rest of the Simpsons apparently go through this after Bart dies.
- Failed Future Forecast: "A Dead Bart Update" reveals that millions of people would die in their sleep on June 6, 2013.
- Flanderization: The narrator describes the Simpsons acting more exaggerated in the beginning.
- Gorn: Implied with the description of Bart's corpse, as well as the ending scene.
- He Really Can Act: In-Universe, the Simpson family crying after Bart's death is described by the narrator as having "better acting than you would think possible".
- Leave the Camera Running: Act Two consists entirely of the Simpsons crying. The crying gets more realistic while the animation, conversely, gets even worse than before and more surreal.
- Not the Fall That Kills You: Subverted. Bart is sucked out of the airplane and is seen on the ground dead, but what part actually killed him is not discussed.
- Nothing but Skin and Bones: Homer, Marge, and Lisa are depicted as such in Act Three.
- Off-Model: The animation is described as less stable than the original "Some Enchanted Evening", and that's saying something. As the crying scene continues, the animation gets even worse.
- The Prophecy: The ending suggests the end of the world.
- Silent Credits: The creepypasta mentions the episode's credits as being silent.
- The Stinger: The cartoon ends with a realistically drawn (and possibly dead) Simpson family sitting on their couch.
- Surreal Horror: Both the story and the episode is scary because of the description of strange imagery and occurences.
- Time Skip: Between acts two and three, one year passes.
- What Happened to the Mouse?: Maggie and the pets disappear without explanation during the last part of the show. It's implied they've died somehow, possibly from not being taken care of properly by the grieving Simpsons family. Or maybe removed by the authorities.
