In Ancient Rome, Gordus Antonius had his slaves fight in the Colosseum. Obeseus the Wide fought against Wolfus Rein and won, to the shock of the crowd. Obeseus then became a crowd favorite in the arena until he was freed from being a slave.
In Italy, Lisa spots a bus with a poster advertising Krusty the Clown's performance in Pagliacci. They meet up with him at the Colosseum, and he puts them in as extras. However, Sideshow Bob, Francesca Terwilliger and Gino Terwilliger find them and corner them on the stage while Krusty who is getting booed by the audience, went into a trap door and flees the stage, allowing Bob to perform the climax of Vesti la Giubba, (which his performance gains a standing ovation). Before they can kill them, though, Krusty's limo picks them up. The Terwilligers walk away with evil smiles, no doubt plotting revenge.
