Krusty gives a free trampoline to Homer, who places it in the Simpsons' back yard. Bart and Lisa are thrilled, but Marge frets it may be dangerous. Homer ignores her fretting and charges neighbors a fee to use it. When scores of people are injured, Homer heeds Marge's advice to get rid of the trampoline. After several failed attempts to dispose of it, Bart suggests chaining it to a pole to tempt thieves with the challenge of stealing it. Soon Snake breaks the chain and takes it.
