Shout out to the TV Tropes analysis page for Dead Bart for banger lines such as:
(content warning for mentions of death and Bart's corpse, religious comparisons)
Bart breaks a window on the plane and is sucked out, and the meaning of the creepypasta's title is finally resolved. Bart dies.
(...)
but to kill Bart Simpson, the preeminent bad boy of the 90s? That only happens in urban legends.
(...)
The revelation of Bart's corpse (and of course there is a revelation, for what use would there be in hiding it? That's what we've come here to see.)
(...)
The revelation of a dead Bart cannot be covered up; it has fundamentally changed the world, and his death imagery, like Christ at Golgotha, becomes a symbol of that change. But Bart is the son of Homer, not God, and there will be no resurrection for this authority-undermining scamp.
(...)
Bart's death heralds the Apocalypse. He is the pale rider on his skateboard.
Bart breaks the window on a plane and is sucked out. Failing on sky hit in the ground After his death, his family apparently sit at their kitchen table and cry for an entire Day before going to visit his grave.
Konata: (serious) “I swear, I saw it. There’s an episode of The Simpsons where Bart dies. It’s real.”
Kagami: (crossing arms) “Oh, give me a break.”
Tsukasa: (nervous) “D-Dies? Like, for real?”
Konata: (nodding) “Yeah. It wasn’t some funny Halloween episode or a dream sequence. It was like… disturbingly real. He falls out of a plane or something, and then the whole episode is just the family grieving. No jokes. No music. Just raw misery.”
Kagami: “And you expect me to believe this aired on TV?”
Konata: “No, no, that’s the thing! It didn’t! It was banned! Hidden! Like some cursed tape no one was meant to see!”
Miyuki: (adjusting glasses) “That does sound similar to the ‘Dead Bart’ urban legend that circulates online. Supposedly, Matt Groening created an episode so disturbing that it was never officially released.”
Tsukasa: (wide-eyed) “Like that Squidward’s Suicide thing?!”
Kagami: (groaning) “Ugh, not this creepypasta nonsense again.”
Konata: (grinning) “You say that, but how do you explain what I saw? The grainy animation, the hyper-realistic corpses, the way the characters just stared at the screen like they knew you were watching…”
Kagami: “I explain it by saying you probably fell asleep watching Treehouse of Horror reruns and had a weird dream.”
Konata: “Oh yeah? Then how come I remember the ending?”
Tsukasa: (nervous) “What… what happens at the end?”
Konata: (leaning in dramatically) “The episode just… lingers on Bart’s grave. The camera slowly zooms in. No music, no sound—just wind. Then, for a split second, there’s a frame of Bart’s decayed corpse in the coffin.”
Tsukasa: (horrified) “Whyyyy would they make that!?”
Kagami: (rolling eyes) “They didn’t!”
Konata: “Believe what you want, Kagamin, but I know what I saw. And guess what? If you search hard enough, you can still find clips online.”
Miyuki: (thoughtful) “Most of those clips are likely fabrications created by internet users who enjoy spreading urban legends.”
Konata: (smirking) “Or… they’re covering it up.”
Kagami: “You need to spend less time on the internet.”
