When Lisa agrees to participate in a Krusty-sponsored "Li'l Starmaker" competition, she panics when another contestant performs a better rendition of "Mockingbird." Thankfully, Homer saves the day by hammering out a manipulative tune about Springfield that leads Lisa to victory. With a win under his belt, Homer becomes a star-crazed stage father/manager, who ultimately drives Lisa to fire him. A distraught Homer counters by taking Lisa's rival, Cameron, under his wing to groom him for the finals.

Financial trouble inspires Ned to rent his rumpus room to a pair of college-aged women, who end up running a soft-core webcam from the Flanders' home without their knowledge. When Ned becomes the laughingstock of Springfield and moves his family to their dream town, "Humble, PA - Home of the Humble Figurines," an unruly neighbor moves in, forcing Homer to beg for Flanders to return. Jason Bateman guest-stars as himself. Later, after Bart is falsely blamed and then expelled for a mishap at the school-sponsored Medieval festival, Fat Tony, guest-voiced by Joe Mantegna, suggests to Marge that he enroll in a private Catholic school. After a rough introduction with a nun on his first day, Bart meets and instantly likes an Eminem-quoting priest named Father Sean, guest-voiced by Neeson. Father Sean shows Bart the cooler parts of the religion through graphic stories and comic books. Bart's growing interest alarms his parents and ultimately drives Homer to visit the church. He, too, finds himself attracted to the religion after Father's offerings of beer, pancakes and games. It's up to Marge to bring her family back to their roots.
