The Priest replies: "What priest isn't?" and is told by Glutton's wife to put a sack over his head and to go into the room of pleasure, which is actually the balcony where Glutton would've been executed; instead the Priest gets executed and his head bounces onto the ground, where kids start kicking him as a ball

The Greatest Story Ever Holed

The Greatest Story Ever Holed title card

In a parody of The Greatest Story Ever Told, the Springfield citizens go to see the activation of Springfield's Subatomic Supercollider, which was built instead of a new baseball stadium, due to lobbying of Lisa. Professor Frink activates the machine and it works, but nothing exciting happens, and everyone blames Lisa for her suggestion. After everyone leaves, two particles collide with each other and create a small black hole which floats off. Lisa cries on the ground, but then notices that her tears are floating towards a black hole. Lisa realizes that she must move the black hole, otherwise it will continue to absorb other people, as it sucked up Ralph and Nelson. The Simpsons put it in the basement and Lisa tries to convince them not to throw any matter in black hole, otherwise it'll expand and may destroy Earth. But Marge, Homer and Bart secretly throw junk at the black hole - Marge puts their grease (because it attracts raccoons) and Bart tries to put his math homework in, but the black hole doesn't accept it, so he puts Edna Krabappel in the black hole.

Black hole attacks the Simpsons

The next morning, the black hole grows bigger and sucks up almost all of the Simpson's stuff. Lisa asks the family if anyone threw anything in it and family denies. Then Lisa spots Snowball V is missing and Santa's Little Helper shrugs too. Other citizens of Springfield gather to put their trash to the black hole, because Homer opened his own business - Magic Craphole Waste Removal. The Simpsons house is sucked into the black hole too, and the other Springfield citizens continue to throw their junk at the black hole - Comic Book Guy throws Disney's Black Hole in and Horatio McAllister attempts to put a big fish skeleton in. Lisa tells everyone that if one more thing gets sucked into the hole, it could reach critical mass. Meanwhile, Milhouse is playing baseball and hits a home run. Suddenly, the ball gets sucked up into the black hole and it grows very intense, sucking up Springfielders, except Maggie. The black hole sucks up Maggie's pacifier and sucks it, going off into the distance and leaving Maggie knowing she stopped the black hole.

Meanwhile, the black hole acts a gate to inter-dimensional travel, so the Springfield citizens end up on a distant alien planet, where their junk is treated as 'treasures', the aliens having built their society around it. The aliens' favorite magazine is the Presidents' Day mattress blowout sale insert and their favorite food is banana peels. The aliens say that they listen to music on the most wonderful device ever created - The Zune. Homer tries to tell them that this is only old junk, rather than treasures, but Marge covers his mouth and tells to aliens to enjoy it.

Unnormal Activity

Unnormal Activity title card

In a parody of Paranormal Activity, Homer sets up a camera at 11:15 AM near the mirror filming himself, and says that strange things happen in the house. He says, "that if anyone finds this footage, after we're missing or dead they should remember him as a hero". Bart and Lisa suddenly come up, because Homer forgot to pick Bart up from Little League & he threw the car keys in Lisa's bean plant, with Ned claiming that the camera is his. At 10:22 PM, Homer sets up the camera in his and Marge's bedroom, and asks Marge if she wants to snuggle. Marge says that she won't snuggle with the camera on, yet Homer tries convinces her that the camera is off, albeit unsuccessfully. At around 3:08 AM, the bedroom door opens and the duvet is lifted off the bed and onto the floor. Also, the cupboard is lifted and a golf club is lifted up in the air, which hits Homer four times and is dropped on the ground.

Around 4:42 AM, the two are woken up by a loud noise downstairs. Marge heads downstairs while Homer takes the camera, although he tumbles down the stairs. Homer and Marge find the family room destroyed and Lisa wants to know why this is happening to them. Marge claims that she doesn't know anything and Homer tells Lisa that every night a mysterious invisible-being from hell waits for a family to go to sleep, then kills them. In the living room at 1:15 PM the next day, Raphael fits more cameras in the Simpson house, and ensures Homer that if anything strange happens, the cameras will pick it up. At around 11:14 PM, Milhouse is asleep in Bart's room, and in Lisa's room two seconds later. In Homer and Marge's bedroom, Marge wakes up, walks around and watches Homer for 4 hours. Homer wakes up, says "hello" to Marge, hears her growling and tries to take her to have sex with him. At around 4:09 AM, Homer pees in the bathroom, but Marge comes, watching him for over 20 minutes. Both of them remain where they are for another ¾ of an hour.

The devil captures Patty and Selma

At about 2:07 PM, Chief Wiggum tests fire in the Simpsons' family room and says that it's hell fire. He also says that someone made a deal with the devil and the devil wants his due. But he gets scared of the cuckoo-clock, and after that he enters back in the family room now as a skeleton and says that the devil feeds on more than fear before collapsing. On Night 15, at 1:23 AM Maggie's blocks and door vibrate. Maggie levitates, is put into a baby carrier, and a bag is placed on the baby carrier, which a bottle has been put into. And then Marge comes to take Maggie back, but someone says that they had a deal. Homer and Lisa come into room, and Bart runs to the room, throwing baby powder on the "mysterious" creature, which is a devil resembling Moe. Marge cries and tells the family that when she was an 8-year-old girl, she saw her 15-year-old sisters Patty and Selma in the attic hailing Satan. They tell Marge that they're doing so because there is nothing good on TV, they have no boyfriends (although Patty is a lesbian), and they are bored.


It worked, but the devil wants to take Selma and Patty. Marge asks the devil to come back for her sisters later, and the devil agrees, telling Marge she bought herself 30 years but after that, he will come back to take her favorite child. Lisa says that she is supposed to be Marge's favorite, but after devil grabs her, she denies that she's the favorite. Homer asks the devil if there is another deal he can accept. The deal is a three-way, and Homer asks if it's between Satan, him and Marge, but Satan says that it's between Homer, him, and another devil. At around 3:30 AM, Homer asks the devils for the safety word, which is cinnamon. Homer wants that they should try something new, and throws his dressing gown at the camera, and the devil shouts "Cinnamon" repeatedly.

Bart & Homer's Excellent Adventure

Bart and Homer's Excellent Adventure title card

In parodies of the movies Bill And Ted's Excellent Adventure and Back to the Future, at Android's Dungeon & Baseball Card Shop, Bart complains about the price of Radioactive Man comic price to Comic Book Guy. Bart tells Comic Book Guy that it's not fair that he's charging $200 for a comic that says 25¢ on the cover. Comic Book Guy tells Bart that the only way to purchase the comic at the cover price is to go back in time to 1974. Bart adds that it's impossible, but when he looks at a Fantastic Foreshadowing comic (it was written "The Boy Who Went Back to 1974", showing Bart in a red car on the cover), he stepped outside, where suddenly he saw a red car come out of nowhere and Professor Frink stepping out of it, telling Bart that is a time machine. Frink asks Bart to hold his keys while he grabs some lunch, but Bart gets in the car and travels back to 1974.

Bart then goes to the Android's Dungeon and Baseball Card Shop's grand opening and buys the Radioactive Man comic, but throws it the trash later, as it is "too preachy" to him. He walks by the window outside the boys bathroom at Springfield High School, while Principal Dondelinger is telling off a teenage Homer Simpson and a teenage Barney Gumble for smoking. Bart gets shocked and walks into Springfield High School. In the detention hall, Homer meets Bart, who explains to Homer that he's his unwanted son from the future who killed all his fun. The young Homer then gets angry and strangles Bart. Then, young Marge Bouvier enters the room and sits down, while young Homer is still strangling Bart. Young Marge gets disgusted by young Homer's behavior, but young Homer asks her to go to prom with him anyway, but she refuses and walks to the rear.

Homer tells off Bart because it was love at first sight and he ruined it. Marge then says that it wasn't love at first sight, and Homer says "What do you know?" Marge says that she knows who she's in love with, and Homer says that she's looking at him. Marge calls Homer an idiot, and Homer returns the favor - shocking Marge. Homer tells Marge to not act like it's the first time someone mentioned that to her - but that backfires, because it is the first time someone has said that to her. Young Homer harshly tells young Marge to shut up and go to the prom with him. Bart wonders, what will happen with him in the future, after he distracted young Homer from young Marge. He grabs his myPhone to check his future. At first, his normal future picture disappears, making Bart think he won't exist anymore, but after that, a picture of him appears, standing near fancy house, which Bart claims 'a hell of a better life'. Then, he convinces young Marge to not marry young Homer, which she agrees to. Bart gets back to present, and young Homer jumps in the time machine's trunk. While young Homer is in the present, he claims his life is ruined, but after that, he sees a poster for Ken and Harry's Cookie Dough Ice-Cream. Then, he sees a shop window, where Itchy and Scratchy is played on huge screen TV's, and gets shocked, when sees an ad for Thursday Night Football. He also comments that the globe is so warm and that he is in awe at the future. Chief Wiggum then passes the street, asleep on a Segway. Homer says that that's not so great. Bart then goes to his fancy house, where Marge is making a smoothie for Artie Ziff. Bart is shocked that his mother is married to Artie Ziff (the man who molested her on prom night), which makes Bart Bartie Ziff. Bart lifts his cap and instead of spiky hair, he has curly hair. Bart yells "Oy, caramba!" and sees his sisters Lisa and Maggie having curly hair too. Artie greets Bartie and tells him to enjoy his luxurious life - and his own bully butler - Nelson Muntz. Bart tells Nelson to give himself a wedgie. Young Homer watches them from the window.

United Federation of Homers Through History

Then, present Homer tells off young Homer, because it was his peeping tree but then realizes that the teenager on the other branch is actually young him. Homer asks why he is in the present. Young Homer says that he traveled through space and time to make Marge settle for him because she doesn't know better. Homer tells Young Homer that if they put their heads together they can think of a plan. Young Homer then questions Homer about what happened and how he lost all his and is extremely obese. Meanwhile, Bart is using a whip to make petals fall off a daisy - which is in Nelson the butler's mouth, saying "I love my life" and "I love it not", similar to "Love me - Love me not" game, while Artie watches. Artie tells Bartie that he's just like Indiana Jones, a role played by Richard Dreyfuss in their universe. The doorbell rings and at the door is Homer, who has come to take his life back. Artie says that he knew this would happen, so he mastered Brazilian jujitsu. Homer then invites the United Federation of Homers Through History and Artie and Bartie roll their sleeves up and clench their fists. Five minutes later, they manage to beat all the Homers. Present Homer tells the guys to regroup - even though he's in a tree. Their plan is to come back with more Homers and start fresh in the morning. Then, Marge comes and is startled. She looks at all the Homers and the Opera Homer asks Marge what she is doing there. Marge says that she realizes that she married the wrong man, and comforts the 'poor, sweet, simple Homers'. She says that she was supposed to be with all of them. Caveman Homer then grunts while trying to speak normally, and Marge says that she meant him as well. Marge tells Homer that she wished that twenty years ago, she should've chosen love. Marge and Homer kiss while the other Homers look on. In normal Simpson house, all the Homers are watching TV, when Marge comes in and ask why none of them had time to take out the garbage. Opera Homer says that Egyptian Slave Homer should do it. The Egyptian Slave Homer grumbles, because it's always him and the other Homers laugh.

However, in the alternate ending of Bart and Homer's Excellent Adventure seen in a video on YouTube a week after the episode, it shows that the other Homers are wiped from existence and everything is back to normal. Before Artie Ziff is wiped from existence too, seeing Homer and Marge kiss, he sadly begs Marge if he could kiss one last time, seconds before he disappears. As Homer and Marge finished their kiss, Marge is glad that it's back to the status quo, before a small second head pops up from Homer, telling him to ask Marge if she has a little sister.
