Images From the Top Ten Simpson's Episodes of all Time.

#5. "Treehouse of Horror VIII" Season 9 Almost all the "Treehouse of Horror" episodes qualify for the list, but this was the best of the best with "The Homega Man" (Homer vs. mutants), "Fly vs. Fly" (a spoof of The Fly with Bart as the bug monster), and "Easy-Bake Coven" with Marge as a green-skinned witch. Classic.
