Opening Credits: Blackboard joke: I will not trade pants with others. Couch gag: The family runs in and sits on the couch, and a hidden Maggie pops out of Marge's hair.
Act One: The episode begins at Moe's bar where Homer is badgered by Moe and Barney to tell the story of his adventure in Capital City, Homer reluctantly agrees. His story begins with himself and his family, as they attend a Springfield Isotopes baseball game, as part of the nuclear power plant's employee appreciation night. They arrive to the ballpark in a charter bus driven by Otto. At the game Homer and the rest of the family are enjoying themselves and having a good time, when to Homer's dismay Mr. Burns sits right next to him in the stands. Surprisingly though, Homer and Mr. Burns strike it off and have a great time together at the game. In the bottom of the ninth, even with the winning run stepping to the plate for the Isotopes the crowd is clearly not into the game. Homer, unhappy about the crowd's lack of enthusiasm for their hometown team, steps out in front of his section in an effort to rally the crowd into a cheering frenzy. As "Baby Elephant Walk" plays in the background, Homer does a crazy little dance and as the crowd starts to wake up and cheer, the batter at the plate hits a walk-off home-run to win the game. In the parking lot after the game everyone crowds around Homer applauding him. Antoine "Tex" O'Hara, the owner of the Isotopes approaches Homer and asks him if he would like to be the full-time mascot for the Isotopes. Homer accepts and while he tries to decide what his mascot name should be, someone from the bus calls out and refers to him as Dancin' Homer, and the name sticks.
Act Two: The next day at dinner, while the rest of the family eats, Homer walks into the kitchen and shows off his new mascot costume. He wears a red cape, shorts, and suspenders and sports a white t-shirt with a giant H on the front. Cut to a montage, as "Baby Elephant Walk" plays in the background, of Homer dancing and performing for the crowd at the stadium, while the Isotopes go on a winning streak. Homer becomes more of an attraction than the Isotopes, and his name becomes bigger and bigger on the stadium marquee each time he appears. Eventually the win streak comes to an end and when it does the team owner calls Homer up to his office at the stadium. In the office Homer thinks his is being fired, while the purpose of the meeting is to let Homer know he has been called up to the big leagues. The Capital City baseball team wants him to fill in for a couple of innings a night for their mascot, the Capital City Goofball. Fast forward to Homer at Moe's bar who emphasizes that his was the biggest decision the Simpson family would ever make. Cut back to the story where Homer is at home informing everyone of his new job possibility. At first the family is reluctant to move but Marge tells Homer that if being a big league mascot is his calling then she is behind the decision to move to Capital City. Homer requests a leave of absence from the power plant, his supervisor, excited that Homer will be gone for a while, quickly grants him a leave for as long as he wants. The Simpson family has a yard sale, Bart and Lisa say their good-byes to their friends and after Homer gives a farewell speech at Springfield Stadium the family is off to Capital City.
Act Three: The family heads to Capital city and a montage ensues complete with Tony Bennett singing "Capital City" in the background, while the Simpson family tours Capital City in awe. In their hotel room the night before Homer's big league debut, Homer nervously practices his routine. The next day at the ballpark, before the game, Homer meets the Capital City Goofball and is informed he will fill in during the fifth inning. Later he gives Marge and the kids their tickets and they wish him luck. When the fifth inning finally comes around Homer stands out on top of the dugout and performs his "Baby Elephant Walk" routine, however no one in the crowd is amused and Dancin' Homer isn't received very well at all. After the game, Homer is called into the owner's office to be fired. A dejected Homer is surprised to receive cheers from his supportive family and they all head back home to Springfield. Fast forward to the bar where everyone has been hanging on Homer's every word. They all beg him to tell the story again, and Homer feels good about himself as he realizes he is once again the center of attention.
