“Take thy beak from out my heart / And take thy form from off my door.” (7F04)

This was the original Treehouse of Horror, and even if you were to accept the idea that the first two sketches aren’t much good — which is a pretty dubious proposition — the final act pushes this over into greatness. Other versions of Treehouse of Horror might be funnier, or more creative, but “The Raven,” as portrayed by “The Simpsons,” is one of those divinely inspired comedic moments, the sort of thing that changes the way you see the original work forever. I cannot now read “The Raven,” or even hear bits of it, without immediately picturing Homer as the antagonist, or Bart as the Raven. And so far as I’m concerned, the poem really does go “– here I opened wide the door — this better be good — darkness there, and nothing more.”

As far as one-off sketches go, it’s one of the best things this show has ever done.
