The Simpsons sit down as normal. Homer rips off a latex mask from his head, and reveals himself to be Sideshow Bob. Bob then brandishes a knife and chases after Bart, with the rest of the family cowering in fear.
When Homer nearly gets killed by a repeatedly closing garage door, Marge suggests that he gets health insurance (pausing to stop him choking on a closed window). However, Homer is considered uninsurable. so Marge starts saving money by cutting corners, which doesn't work very well when Homer wastes it faster than Marge saves it. Marge insists that she takes charge of the family finances, resulting in Homer using the savings on the down-payment for an RV. Marge has finally had enough, and stops talking to him, so Homer seeks out some new friends - fellow RV owners, whom he invites to pull into his backyard. However, their problems disappear the next morning; the problem is, so do Bart and Lisa, who decide to drive the RV back to the sales lot.
Marge takes the kids on a random and pointless Sunday drive but Homer gets out of it by cleaning the garage. Homer, however, barely does anything. Lifting up a box, Homer looks up and screams as some spiders fall on his face. He tries to kill the spiders by spraying himself in the face and screaming: "WHAT?! SPIDER POISON IS PEOPLE POISON?!" He then trips on Bart's skateboard and falls on the ground under the garage door. He sees a spider and tosses a TV guide magazine at it, but the magazine hits the garage door button and closes the door on his neck and continues trying to close. When Marge and the kids get home, Homer is dead. Bart tells Lisa to open up the envelope he gave her. Lisa opens up an envelope and pulls out a drawing of Homer crushed under the garage door with "THIS IS WHAT WILL HAPPEN" written under him. Lisa and Bart perform CPR and revive him. Marge then declares life insurance but due to his fitness, constant accidents and multiple physical ailments Homer is declared uninsurable. Marge then watches a movie (which claims to be based on a true story) on TV known as "From Homemaker to Homeless" about a rich housewife who becomes poor, insane, and ugly after her husband dies of a heart attack and she has no life insurance. Marge then gets a nest egg to pay for Homer's insurance and buys imitation brands of cereal, soup, coffee, forces Bart and Lisa to wear church charity clothing to school, and has Homer bring his own drinks to Moe's Tavern. Homer is then kicked out for bringing an outside drink and decides since the nest egg is making his life miserable he should purchase something cool. Homer then buys a fully loaded RV which he has the kids living in as well.
Homer then goes to a gas station where he meets a couple based on George and Martha from Who's Afraid of Virgina Woolf and Homer then invites them and their friends to his backyard. However, they are getting on Marge's nerves and Homer's friends leave after Marge cuts out the power. Marge and Homer then get into a fight and Bart and Lisa have no choice but to take the RV back to the dealership.
Marge and Homer then follow Bart and Lisa to the dealership in the car. The bad thing is though Bart and Lisa miss the dealership and end up on the freeway and the map for the dealership is The Flinstones Fun Map which has a note saying "Dino short for dinosaur? Remember to Ask Jeeves.". They soon get into more trouble when they end up on a Turkish import ship and are about to be taken to Turkey. Marge however gets them to stop by giving them the 300 cans she bought (although she wasn't willing to give them a cornerstone if they asked after the captain said "it's a shame that [Marge] dressed like a Lebanese Prostitute). The family then has dinner on the Turkish import ship, and Homer vows to return the RV the first thing in the morning while lifting it up via a crane. He then carefully places the RV on a dock, but the dock breaks and causes it to fall in the water, much to Homer's annoyance, while Cowboy Bob blabbers on about his victory. Surprisingly, Marge takes this very well, although the Turkish crew reveal to Homer that they slipped some hashish in her dinner to loosen her up.
