Moe's Tavern is closed by a health inspector, so Homer takes out a mortgage on his house to open the bar again. As a result, Marge becomes Moe's business partner and turns the bar into a British pub that makes them spend too much time together, which worries Homer.
Homer finally pays the mortgage and The Simpsons celebrate by going to a fancy restaurant for brunch. However Bart and Lisa get into a fight and Homer goes to Moe's Tavern to escape his family. At Moe's the health inspector comes who ends up being a good friend of Moe and passes him in everything. However the health inspector eats a pickled egg from Moe's pickled egg jar and dies. A week later a more competent inspector comes and shuts down Moe's Tavern. A funeral for the tavern is then held and Homer decides to help Moe bring the tavern up to code. To get the money to do this, Homer takes out a second mortgage on his house. Marge is mad about this and becomes Moe's business partner and believes Moe's customers should be higher class. Marge then suggests that Moe's should become a British pub known as the Nag & Weasel and soon Moe starts renovating.
Moe's Tavern then goes from dive to fancy bar and then Marge helps Moe with his new business. Homer in the meantime is going to bed and wants to make out with Marge however it is 4 in the morning when Marge comes home and Homer believes Moe is trying to get Marge to have an affair with her.
Homer and Marge then go to a movie and are joined by Moe. This then frustrates Homer and then on a trip to Itchy & Scratchy Land with Lenny and Carl. They say that Marge will have an emotional affair with Moe and there will be nothing Homer can do about it. Marge and Moe are then invited to a bartender convention in Aruba via a plane and Homer tries to win Marge back. Homer then rushes to the airport with Chief Wiggum and then Homer gets to the plane when it is airborne and then comes out of the toilet. Moe in the mean time finally found his true crush and decides to marry Marge. However, Homer catches up with Marge in the mean time however more chaos strikes when Homer opens up the door of the plane while it is airborne and almost everything on the plane is sucked out including Mr. Teeny however Homer closes the door in time. Marge tells Moe that she does not love him and that she will never leave Homer. The threesome then land in Aruba and Moe attempts to drown himself after Marge got back with Homer. Marge reassures him that he can find someone if he changes his personal hygene habits. In the mean time Bart has entered himself, Lisa, and Maggie in a hot air balloon race in La Vie En Rose.
