When all the fast food restaurants in Springfield become healthy, Homer turns to the last bastion of greasy food for comfort - and digs up some childhood memories along the way. Meanwhile, Lisa must find a good news story when the future of her school radio station is in jeopardy.
The episode begins with Homer knocking down a load of Domino's pizza boxes as though they were dominos. It's this huge thing that ends with nuclear pizzas being dropped into the mouths of himself, and his friends. Mr. Burns then comes in and tells them that because Homer won a button counting contest, they're all free to take the rest of the day off. Homer drives back home, wanting to celebrate his happy day with his family, but then he realizes that Patty and Selma's cars are parked in his driveway, much to his dismay. Patty and Selma make the family go to the 24th annual DMV awards, which is a car-related award show that they'll be hosting. Homer leaves the place in rage and leaves his family behind. He tries going to Krusty Burger, but they've taken all the meat off the menu and replaced it with vegan food. Homer drives around town, seeing that all restaurants have done this too. He comes across a rusty old trailer, where everything is unhealthy and disgusting. The next day, Homer tells his family everything about it. Grandpa tells him that when he was a boy, he used to take him there all the time. When he and Mona argued with each other, they went to a marriage councilor, which was next to the hot dog stand. They left Homer there and the guy who worked there gave him hot dogs, which made Homer start eating away his misery. Back in the present, Patty and Selma had lost all their money in a bet at the DMV award show, so they're going to live with the Simpsons for a while. Meanwhile, Springfield Elementary is having a radio show, run by the 4th graders and Lisa is included. Everyone else on the show is acting ridiculous and Lisa's the only normal one. Eventually, Homer's attendance at the hot dog stand brings popularity to the store, meaning that the Krusty Burger is losing customers. Lisa does an interview at the detention and the radio station gets shut down. Lisa feels bad about it, so Homer brings her to the hot dog store to cheer her up. When he gets there, the stand had been shut down by the health department, due to Krusty ratting them out. Krusty then buys out the stand. Homer denies this and he ties the restaurant stand chain to his car and drives off, taking the hot dog store with him. Homer ends up on the news. When the fat people hear about this, they side with Homer and help him achieve his goal, when Krusty tells the other restaurant mascots about it, an army of mascots, led by Colonel Sanders goes against them. On their drive, the stand, with Homer in it, goes off a bridge and is dangling from the chain. The man who used to run the stand comes back to Homer and saves him, telling him that he doesn't need the stand, and that the only reason why he thought it was so sacred is because it helped get him through some tough family times, not because of the content of the restaurant. Homer gets back up and lets the stand go overboard and he doesn't get justified for what he did and the episode ends.
