The ghost: With its annual "Treehouse of Horror" episodes, a ghost or two would surely cross paths with Homer and Co. One memorable haunt belongs to the 2000 edition, when Homer became "G-G-Ghost D-D-Dad." The skinny: A horoscope tells Homer he will die, and eating vegetables does him in. When he gets to heaven, Homer is told he cannot gain entry until he completes one good deed. Boo who? Everyone in Homer's life, be it Bart or Principal Skinner's mother, Agnes. Homer's attempts to complete at least one good deed result in the wrecking of others' lives. Homer is damned to hell, where Satan gives him noogies.
