Goodgulf:
So a while ago I was looking writing a Christmas story dealing with the "Assistants" of Santa Claus. Eg: Belsnickel, Knecht Ruprecht, Krampus, Zwarte Piet (Black Pete) etc - they handed out beatings and otherwise punished naughty children.
Nods. I've enjoyed several very good stories where Mrs. (or Ms.) Claus does the same thing, often with adults.
