My favorite holiday movie, and subsequent gif, are from Rudolph the Red Nosed Reindeer, the claymation version. I have loved this movie for as long as I can remember, and something about the sheer amount of work that must have gone into it to make it just right, makes it my all time favorite. This gif in particular is my favorite because it shows Rudolph and Hermey, both of whom have a special place in my heart, AND I love the aesthetic with his cute lil nose glowing.

EDIT ;; Edited my reply because I cannot human and had the wrong link/code in there to show the gif. x.x
