Christmas movies and specials are a big part of the holiday for me, as I suspect it is for many people. I also have some episodes of my favorite shows that are set around Christmas or New Year that I get out or find streaming every year.
I'm not going to put in where I know the episode can be watched because I know that can change often, and I'm too lazy to come back and catch it up.
Community- Abed's Uncontrollable Christmas, Season 2
I actually like this episode better now than when it first came on. The more I watched the show, the more I liked the character Abed. This entire episode is in stop-motion animation. No one in the group can see the animation that Abed sees, and most of these characters are really not interested in a big, sappy finale, but they realize that it's what Abed needs and they rally around. Abed sings a "sad, quick Christmas song" that, for some reason, gets stuck in my head about once a month, year-round. It's a real earworm.
Community- Comparative Religion, Season 1
Shirley tries to enforce her Christmas values on the group with her Christmas party, and is disappointed when she finds out that Jeff is going to be in a fight. This is the origin of the "Its December 10th!" meme. Also, O Christmas Troy.
Community- Intro to Knots, Season 4
Annie invites the group's history teacher to their Christmas party to try to get a better grade, and Chang ties him up.
Miranda- The Perfect Christmas
Miranda's parents get on her nerves more than usual around Christmas, and when they publicly embarrass her with a song at their Christmas party, she revolts. She goes back to her apartment and invites her friends for a more relaxed Christmas.
The Office (American version)
I'm not going to write a little synopsis for these, because I've watched them so many times that I'll likely start typing a transcript from memory. So I'll just put in some of my favorite bits.
Ranked from my first to least favorite (which is still awesome)
Dwight Christmas, Season 9 (very impish)
Secret Santa, Season 6 (a woman has uslurped my position)
A Benihana Christmas, Season 3 (I miss the days when there was only one party I didn't want to go to.)
Christmas Party, Season 2 (nasty Christmas)
Classy Christmas, Season 8 (epic snowball fight)
Moroccan Christmas, Season 5 (My horn can piece the sky)
Christmas Wishes, Season 7 (my treasures!)
Here's a ranking from Collider, if you want another view, even though mine is better and right.
Doctor Who, in chronological order from the 2005 re-boot
The Christmas Invasion
The Runaway Bride
Voyage of the Damned
The Next Doctor
The End of Time, parts 1 and 2
A Christmas Carol
The Doctor, the Widow, and the Wardrobe
The Time of the Doctor
The Husbands of Doctor River Song
The Return of Doctor Mysterio
Twice Upon a Time
The Thirteenth Doctor has New Year episodes instead of Christmas. I have most of the Christmas ones as a playlist in iTunes with all their mini-episodes, so I can watch them in order.
That's all the holiday geeking out that I have time for now, but if there's another TV show with a great Christmas episode, please let me know in the comments.
