Full Story
Bart draws Lisa's attention by talking about the "Hardest Test in the World", which is really a prank. After pranking her, he posts the humiliating photos of her on Instagram. She swears revenge on him.

After the Internet goes down in The Simpson house, Homer pulls out the VCR and him and Marge reminisce on classic TV shows they watched when they were younger.

After the VCR breaks, the family sees Flanders internet working just fine, so Homer and Bart go to steal Flanders router to take for themselves. Bart, trying to retrieve the router, is struck by lightning when Homer is distracted by trying to refresh Google.

The family goes to the hospital, there he is in a coma then. Marge and Homer leave, and Lisa is there. At first she feels awful for what happened to him, but then she takes the opportunity to get back at him for humiliating her.

Bart then in his coma thinks he is back to normal, but then he is visited by the ghost of Maude Flanders. Then after this Marge and Homer come in and ask if Lisa wants to come with them to get something to eat. Lisa denies and says she wants to stay with Bart all night. Afterwards, after Lisa seeing that her picture of her being humiliated got millions of likes, she says she will add the worst thing to Bart's dream, Milhouse Van Houten.

After then, back in Bart's coma, he sets up some crosses in his Treehouse, when Milhouse comes in and asks if Bart is into Jesus now. Maude comes in and explains how that Treehouse looks like the first apartment that her and Ned Flanders lived in. Afterwards, Bart draws her away by Homer Simpson's socks. Milhouse suggests he go to see his doctor, Dr.Samuel Elkins.

When he sees Dr.Samuel Elkins, Bart discovers Dr.Elkins dead corpse behind the couch. Dr.Samuel Elkins claims that he took his own life with Rat Poison five minutes before Bart came in. Afterwards, Bart has the ability to see the dead. He looks out the window to all of the dead snowball cats, Hyman Krustofsky, Bleeding Gums Murphy, and Maude Flanders. Dr.Samuel Elkins proceeds to ask one last wish from Bart, to get revenge on Dr.Morton. Bart is visited by all sorts of ghosts inside of Dr.Morton's office.

Bart then proceeds to do last wishes for some ghosts, like hurt Johnny Tightlips and Fat Tony. And then Dr.Hibbert proceeds to tell Lisa that fooling with someone's brain while they are in a coma could possibly scar them mentally or even kill them.

Lisa then regrets for traumatizing Bart, when Homer comes in claiming that he is dead after walking nine blocks for some Krusty Burger. It then proceeds back to the coma that Bart is in when Maude tells Bart that she wants revenge on his father for causing her death. He then meets the same fate as she did, being shot by T-shirt cannons, but this time, he was shot by T-shirt cannons by the bullies. Maude then proceeds to thank Bart for fulfilling her revenge.

Bart then proceeds to say that he is glad that he has helped all of the ghosts, when Homer's ghosts says except for one. Bart then says that Homer's ghost should stay down there with him so he could fulfill Homer's last wishes. Then the sparkling light of heaven shines down on Homer, that it's his time to go, when Lisa tells Bart to stay with her outside of the coma, Bart tells Homer that he has to stay with them. Saying that Marge would remarry, some else would be raising them, and that somebody else would be riding his lawnmower. Homer is fine with all of this until Bart somehow shoots the light of heaven with a T-shirt cannon. Then Bart almost dies outside of his coma.

At the end they are all celebrating his revival when he wonders how this isn't all a dream, when Milhouse says it's because he isn't wearing the sweater. Then Bart tells Lisa how everybody in the future is going to die after all of this.
