Top 10 Nontraditional Holiday TV Episodes

Happy Festivus, everyone!

To celebrate today (in addition to the feats of strength and airing of grievances), I rounded up the top 10 nontraditional Holiday television episodes over at The Daily Beast, from Community and Seinfeld to Buffy the Vampire Slayer and Doctor Who. (And, yes, It's Always Sunny in Philadelphia's direct-to-DVD special--which just aired on FX for the first time this month--made the list, naturally.)

An aside, I could have filled the entire list with just British television shows, from The Vicar of Dibley and Doctor Who (which both made the list) to Gavin & Stacey, Blackadder, Catherine Tate, Absolutely Fabulous, and about a zillion others.

But I am curious to know: what is your favorite nontraditional holiday episode/special? Putting aside the traditional Rudolph and Charlie Brown Christmas, what are some of the more out there holiday episodes or specials that add that extra spike to the eggnog?

Or make that Festivus aluminum pole shine a little more, anyway?
