Plot
Homer takes Bart, Lisa, and Groundskeeper Willie to the park, where they ride on a merry-go-round. Homer spins them at a normal speed, until Bart tells Homer to spin them faster. Homer is only happy to oblige. At first enjoying the fast pace, the group soon realizes they got more than they bargained for. Groundskeeper Willie flies off the merry-go-round and collides into a tree, breaking his back and planting his teeth into the tree. Lisa is next as the pole she holds onto breaks from the merry-go-round, sending her hurtling towards a chopped piece of wood. She is cut in half and the pole impales her chest.
Bart has the strength to hang onto the merry-go-round, but he finally flies off when his hands break away from his arms. His body is sent flying into a nearby plane's active engine, shredding his body to bits.
Finally, Homer stops spinning the merry-go-round, exhausted from all the effort. The merry-go-round comes to a stop, and Homer sees Bart's severed hands still hanging onto a one of the bars. Realizing what he had done to them, he walks away, pretending not to notice.
