Best Costume: Simpsons as Munsters

The Best Parts From All 23 'Simpsons' Treehouse of Horror Episodes

"The Simpsons" Season 25 opener will be the 24th "Treehouse of Horror" (well, technically, only the 12th, since the episodes were called "The Simpsons Halloween Special" until No. 13). That's a lot of ironic twists, sci-fi/horror parodies, and bodies. Oh, the bodies: burned, electrocuted, turned inside out and filled full of lead. Producers have used Halloween as an excuse to push the envelope of acceptable animated fare for more than two decades now. Come with us on a ghoooulish tour of beloved holiday traditiooooon. — Robert Chan, Yahoo TV
