PS: The real version of Christmas, where it spawned from, is called Yuletide. It included heavy drinking, animal sacrifices and celebration of women (called Mödraniht - mothers night, which may also had sacrifices). Odin was the Yule Father (The Yule one - Jólnir) who lead the Wild Hunt across the skies (The Witcher) and it also had Dragurs (Skyrim).
Now a fat guy is coming down chimenys to eat cookies. They really nerfed this holiday.
