The Best Halloween-Themed TV Episodes Ever
The 'Big Bang' nerds got into the Halloween spirit (CBS/Warner Bros. Television)
"Castle": "Vampire Weekend" (2009)
Nathan Fillion dressing in a space-cowboy costume that looked suspiciously like his wardrobe in his brilliant but canceled show "Firefly" made this episode a lock for our list. Hearing Castle's daughter say that he'd worn it five years ago and that it was time to get over it was just icing on the cake.
"Community": "Introduction to Statistics" (2009)
This featured each cast member wearing costumes that revealed so much about their inner characters and ended with a heavily medicated Pierce -- dressed as Beastmaster -- and Jeff getting rescued from a collapsing cocoon of chairs and tables by Abed, doing a perfect Batman imitation, gravelly voice and all.
"Chuck": "Chuck Versus the Sandworm" (2008)
There was a plot about some sort of techy whiz kid whom Chuck bonds with, but we were too distracted by the sight of Sarah in a Princess Leia costume to really pay much attention.
"Supernatural": "It's the Great Pumpkin, Sam Winchester" (2008)
When Halloween fun turns deadly (razor blades in candy, bobbing for apples in boiling water), Sam and Dean discover a witch's hex bags at the scene of each crime. The angels believe she's trying to raise Samhain, a demon who's one of the 66 seals that will raise Lucifer, and want to nuke the town, but the brothers persuade them to let them handle it. They fail to stop Samhain from rising, but masks made of blood keep them alive long enough to exorcise him.
"Bones": "Mummy in the Maze" (2007)
Not only did we get to see the cast members in their Halloween costumes -- including Brennan as Wonder Woman and Booth as a nerdy Squint -- but they had to wear them while investigating two mummified women left in Halloween-themed locations.
