Pagliacci

Pagliacci is an opera.

History
Krusty was starring in Pagliacci at Colosseum when the Simpson family was in Italy. They meet him at the Colosseum, and he puts them in as extras because Sideshow Bob, Francesca and Gino had an vendetta on them. When Krusty is getting booed by the audience he 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 and make the audience belive it's fake even fast the Simpsons trying to tell them it's not. Before they can kill them, though, Krusty's limo picks them up.
