Homer buys Bart a Superstar Celebrity microphone for his birthday. Bart thinks it's the lamest gift in the world until he realizes he can play some great pranks with it. One of his pranks backfires when the entire town comes to the rescue of "Timmy O'Toole," the little boy Bart pretends has fallen down a well. Krusty the Clown brings his celebrity friends, including Sting, to record a song "We're Sending Our Love Down the Well" to benefit Timmy. Realizing things have gotten out of hand, Bart tries to undo his prank, but winds up falling down the well himself. He eventually admits that there was no Timmy O'Toole and the whole town is angered because a 10-year-old boy took them for fools. The only people willing to dig Bart out of the well are Homer and Sting.
