For his birthday, Bart gets a Superstar Celebrity microphone that transmits sounds through an AM radio. As a prank, he tosses a small radio down a well in the middle of town and, identifying himself as "Timmy O'Toole," uses the microphone to call out for help. Soon a large crowd gathers. Fears mount when the crowd realizes that rescuers cannot fit down the well's small hole. Krusty and Sting spearhead a video, "We're Sending Our Love Down the Well," to raise money for "Timmy's" rescue.

Lisa discovers Bart's ruse and warns him that he will not get away with it. Bart laughs off her warning until he remebers that he put a "Property of Bart Simpson" sticker on the radio. As he climbs down the well to retrieve the radio, the rope slips, trapping him for real.
