Oh Shinshoku, how I love thee.
I'd like to wear you with a bright yellow speedskating outfit, and do the running man for hours on end at Shibuya crossing.
Sigh...

Santa Claus's origins are from neolithic hunter-gatherer societies in Scandinavia. His red and white outfit is actually what was worn by shaman from this part of the world for thousands of years- but that's not all. Ever wonder what those flying reindeer are about? Well, reindeer actually eat a form of lichen, which after passing through their systems turns their urine into a psychedelic liquid that, when imbibed, gives the partaker a weightless sensation- like flying. This liquid was used by the shaman for divination, and throughout the history of Scandinavian artifacts, we find a Santa look-alike with flying reindeer! Merry Christmas!
