A wild Christmas character is making a devilish comeback. Krampus gets his name from a word for "claw". That's apt for a demon said to grab naughty children and stuff them in his sack. Popular in Alpine villages centuries ago, Krampus scared kids straight -his long red tongue upped the fear factor- and taught them that evils bows before good. He served Santa's forerunner, kindly St. Nicholas, who had "the power to send Krampus back to hell".

Europe once had a roster of Christmas rascals like Krampus, many with pagan roots. And Yule was a lot like today's Halloween partly because farmers had time off from chores and could party with abandon. On December 5, the eve of St. Nick's feast day, folks would bang on doors for food and drink.

But by the 1800s, church leaders had marginalized Krampus. Now he's enjoying a mini-revival, mainly for the fun of it. The Austrian state of Salzburg alone has 180 Krampus clubs, more than half set up since 1990. Revelers roam streets in Krampus garb, rattle bells, and roar. It's a good feast day, but alas, some drink, brawl, even riot take place -frightening kids and adults alike-.

For more information there's a Krampus Museum in Austria.
