The caganer is a cheeky little figurine from the Catalonia region of Spain.  It is typically placed in Christmas nativity scenes, secretly squatting amongst the wisemen, shepherds, and stable animals.  Whereas once the caganer was depicted as a simple peasant, the tradition has since expanded to include historical, political and cultural figures.  Butt you don't have to wait for Christmas to enjoy this funny gag, because, you know, everybody poops.
