Strange Christmas traditions: Spain

Christmas time is the time of being with our families, eating too much, exchanging presents. Apart from that, in every country or even family, the Christmas traditions differ. I find as the strangest tradition I have ever heard about, the "pooing man Caganer" from Catalunya. The man in question looks charming. It a wooden "sculpture" of a peasant man who wears a typical catalan red cup and trousers down taking a poo. The name of this character in a literal translation means "the crapper".
The Caganer comes home on the 8th of December and starting from this day it gets ready for the Christmas Eve. The children fid it with godies, so on the proper day it is ready to poo it out, and in that extraordinary way give presents to the kids. Nobody knows where and when from comes this tradition, but probably it comes from the 18th century.
