With Black Friday and Cyber Monday behind us, it's time to rejoice in the true spirit of the season: St. Nick's seedy underbelly. Since 1994, Santa-clad folks have had a jolly good time storming cities around the world, flooding the streets (and pubs) with red felt, stray reindeer, and cacophonous bellows of "Ho, Ho, Ho!" Today, even the Kremlin isn't safe from what started as a few dozens-deep San Francisco Santa mob. So don Blitzen horns and elf shoes, and fear not the wrath of the naughty list — Santa knows, but tonight he doesn't mind.
