When the morning starts off with Marge finding remnants of pizza boxes scattered around the living room, she hopes that a bear was the culprit.
Instead, Homer's groans lead Marge to find her husband on top of the kitchen table. In nothing but his underwear, Homer receives advice from Marge on his health. Just when Homer seems to be taking Marge's words to heart, he marches upstairs to tell his wife that he will take his health seriously only to fall down the stairs because he's out of shape.
Cut to Homer's funeral at the church, where everyone in town grieves for the Simpson patriarch. Suddenly, Professor Frink interrupts the proceedings to announce that he has made a clone of Homer. Frink reasoned that he wanted to start out with a sheep first but decided he wanted to experiment with a simpler subject.
Marge warns Homer to take this second chance seriously to which Homer asks if she made potato salad for the wake.
Fast forward to Homer's clone's funeral the next day. The third Homer comes in only to die. The fourth Homer falls into the open grave of the third Homer. The fifth Homer electrocutes himself with the toaster. No one knows what happens to the sixth Homer. The seventh Homer lands in the hospital before pulling the plug on himself when he hears that he can't eat solid foods for two weeks.
Thirty years into the future, the Simpsons mourn another Homer except that this time Frink cannot bring Homer back much to the surprise of the family.
Frink did store Homer's memory in a flash drive, which he plugs into a television screen conveniently in the church.
When Marge realizes that her husband is just a face on a screen, she is fed up with him when Homer asks that she reboot the screen. Marge ejects the flash drive to give to Bart, so that Homer can reside with him for.
Bart shows Homer his new digs, an abandoned classroom at Springfield Elementary. As soon as a glum Bart sends his two sons to his ex-wife's house, he needs advice more than ever now that. Homer is of no use when the monitor freezes.
Working at a dino amusement park, Bart laments that he misses his kids despite Nelson telling him that he should be happy that he's free.
Elsewhere at a zombie soup kitchen, as Lisa feeds the undead with synthetic vegan “brain” food, husband Milhouse comes looking for her. A zombie attacks Milhouse, while Lisa's brother continues to hit the melancholy train with Nelson dragging him to a club.
Unable to move on from his ex, Bart sees a targeted billboard telling him to move on using shock therapy that makes him forget about his ex. After the procedure, Bart sleeps with one woman after another, but it's his former flame who still catches Bart's eyes.
Meanwhile, Lisa and zombie Milhouse are attacked by the same old bullies, yet surprisingly, Milhouse saves the day, and Lisa actually finds it attractive because the old Milhouse would not have had the guts to fight off the bullies. Even though Dr. Huber can reverse Milhouse back to his old self, does Lisa want her old hubby back?
Over at Moe's, Bart finds Lisa there drinking. The siblings mull over their love lives before Marge interrupts them on what goes into a real tough marriage, so will Marge's secret to surviving a long-term marriage be enough for her children's relationships?
