Nightmare on Evergreen Terrace (Treehouse of Horror VI, 1995)

If Kang and Kodos are one great Treehouse staple, then one oddly consistent other is a bit more down to earth: Springfield Elementary’s own Groundskeeper Willie, who really comes into his own during Halloween season. Casting him this time as the antagonist in a riff on Freddy Kreuger, not only is this skit actually quite chilling at times, it’s maybe one of the show’s best direct homages to a piece of iconic horror.
