The other tradition it the Caga Tió. While Santa climbs down the chimney to bring us our presents, Caga Tió is the present pooping log. You sing a song, beat him with a stick, and then he shits out your presents. I am not making this up.
shit, log,
shit turrón,
hazelnuts and mató cheese,
if you don't shit well,
I'll hit you with a stick,
shit, log!
