Santarchy!

In response to an earlier post about Santas running riot in New Zealand, SamuraiFrog made this comment:

The funny thing is, every year for the last ten or so years, there have been Santa riots all around the world (they don't always riot, sometimes they just get drunk and march, etc.). But no one keeps track of this stuff; I can't even find a good enough explanation on the internet. But yeah, I'd be surprised if this was the only one this year.

Well, mystery solved. Santarchy is the work of the Cacophony Society, an organization that Wikipedia credits as the basis for Project Mayhem in Fight Club.
