Not sure if this is what you had in mind, but I do love how Doctor Who manages to bring us a new Christmas special every year, even though most of them are only tangentially related to Christmas. XD
Seriously though, I do look forward to seeing the new Doctor Who Christmas special every year, just because I'm such a big fan of the series as a whole. :P I usually don't even go in expecting much of anything Christmas-y. I just look forward to what will hopefully be a good episode of the series in general. XD
But, some years they do some clever stuff with it. Like the 2013 special, which revolved around a town that was called Christmas. You know, so like, the Doctor saves the town from aliens and then you can say that "the Doctor saved Christmas???" Ahahahah... hah... clever.
And then there was the 2014 special -- the plot and premise of which can basically be summed up as "Alien meets Inception meets Santa Claus". ...Because that needed to exist, I guess. ¯\_(ツ)_/¯
In general, though, I'm kind of just amused by the very fact that this show has a tradition of making a new, only-somewhat-Christmas-related special each year. XD
