"Down that well!" was yelled out by Krusty the klown during the song "we're sending our love down that well" while the so- called Timmy O'tool was trapped down a well. The song was sung in style of USA for Africa's 1985 hit "We are the world", which was also sung by a bunch of then popular singers grouped together for a charitable cause. Timmy O'tool was so-called because he was fictionalized by Bart, who made up that name and the falling down the well story as a large prank he played on the whole town. This is a typical " what goes around comes around" episode, where Bart ends up getting a taste of his own medicine. Ahh, sweet karma. The whole getting trapped down the well thing is reminiscent of the real life event of baby Jessica getting trapped down a well in Texas in October of 1987. This episode also had the "mmm...chocolate. D'oh!" joke from Doh'mer, I mean Homer. And of course, there's also the "property of Bart Simpson" labels Bart made from a label maker (one of which was put on something which was to give his little prank away) that he got as one of his dismayed birthday presents we got a short montage from (Homer to Bart before opening his radio present: "I bet you think nothing will possibly top that cactus")(Homer when seeing a "property of Bart Simpson label on a beer: "ohh, there's only one beer left and it's Bart's).
