I'm not much for potty humor, but this seems noteworthy to me. It has recently come to my attention that Catalonians seem to enjoy something called el caganer, which is a small statue that, ahem, shows someone pooping. What's more: this tradition is steeped specifically in traditional nativity scenes.
I didn't believe it myself when I first read it, or even when I followed the links from that page, but then I checked wikipedia, which verifies the story. They even say that when Barcelona officials tried to eliminate the caganer from its nativity scene in 2005, there was "widespread media criticism."
The subject was even discussed on Stephen Fry's genius series QI. Scat-illogical, perhaps?
