Enraged at being cast as the village idiot and having livestock disrupt his yard at the school's Medieval festival, Groundskeeper Willie sabotages the event and leaves Bart to take the blame. As a result, Bart's expulsion lands him in an affordable Catholic private school where Father Sean, an Eminem quoting Priest, uses graphic stories and comic books to turn Bart on to the cooler parts of Catholicism. Bart's increased interest in the religion alarms his parents and drives Homer to visit the church to put an end to the nonsense. Father Sean lures Homer to the religion over a beer and pancake dinner and closes the deal over a game of bingo. After a marathon confession session, Homer returns to a dismayed Marge who later enlists Reverend Lovejoy and Ned's aid in springing Bart from communion class. Set on bringing Bart back to Catholicism, Homer and Father Sean chase the gang to a Protestant Youth Festival where Marge and the prospect of playing paintball lure Bart back. After a heated public debate, all members agree to disagree under the banner of Christianity and Homer decides he'd rather return to the Protestant Church rather than divide the family.
