Catalonian nativity scenes traditionally include El
Caganer, a figure of a guy pooping with his pants down.
Another Catalonian Christmas tradition is Tió de
Nadal, the Christmast Log. This is a small log
with a happy face and a red hat, propped up on legs. In the run-up to
Christmas, the kids feed the log daily, and then on Christmas Day it
magically poops out nougats, hazelnuts, or other plausible log poop
objects such as dried figs.
To make Tió de Nadal defecate, one puts its end into the fireplace, or,
if no fireplace is available, beats it with sticks.
Tió (“trunk”) should not be confused with tío (“uncle”).
