Homer's burgers is the crossover between Bob's burgers and the Simpsons. It aired on the Simpsons, not Bob's burgers.
The Simpsons decide to take a vacation. When they arrive, they see Bob's burgers. They decide to eat there and see many people outside but no one inside. Homer comes up with a catchy slogan for Bob's burgers and all of the people go in. Bob says that was the most people they've ever had. Homer then gets a job as the slogan writer for a restaurant. While staying at the Belchers House for a vacation, Marge and Linda become housewives of the house, Bart and Gene are thinking of a hilarious tune with farts and laser sounds for the restaurant, Lisa and Tina are saving the horse sanctuary after the news has been announcing it’s shutting down and Maggie and Louise become BFFs and team up together to play fun tricks on enemies.
