The legend of St. Nicolas is a story about an evil butcher who kills, butchers, and salts a group of children and stores them in barrels. Seven years later, Saint Nicolas arrives and asks the butcher for "that special meat in the barrels in the basement". The butcher flees, whereupon St. Nicolas brings the children back to life.
