While Saint Nicholas may bring gifts to good boys and girls, ancient folklore in Europe's Alpine region also tells of Krampus, a frightening beast-like creature who emerges during the Yule season, looking for naughty children to punish in horrible ways -- or possibly to drag back to his lair in a sack. In keeping with pre-Germanic Pagan traditions, men dressed as these demons have been frightening children on Krampusnacht for centuries, chasing them and hitting them with sticks, on an (often alcohol-fueled) run through the dark streets.
