When Bart is sent home from school with head lice and Lisa loses her shoes, Marge and Homer are accused of being negligent parents and their kids are taken away by the bureaucratic do-gooders at the Child Protection Agency. As (bad) luck would have it, Bart, Lisa and Maggie are placed in the foster care of the Flanders family. While their kids must endure 5 PM bedtimes, Flanders-style nachos, and endless games of Biblical Bombardment, Homer and Marge must attend a special class for bad parents. Ned treats Bart, Lisa and especially Maggie with love and kindness, until he discovers that none of them have been baptized. After a fainting jag, Ned shores up the energy and the righteousness to baptize the kids himself. As Ned leads his new flock to the edge of the river for their baptisms, Homer and Marge, newly graduated from bad parent school, rush to the scene to stop him. Homer sees what is about to happen and dives into the river to prevent Ned from pouring Holy Water on Bart. When the Holy Water hits Homer, it burns his flesh and bubbles up. Bart, however, is saved from salvation and the Simpson family is reunited.
