I'll never forget reading a story about the Spanish guy who got crushed by a rock while having sex with a chicken. It was in the school newspaper and it was the first time my young and innocent self was conftronted with this phenomenon of people having sex with animals.

I remember the article having a different picture though... imagine how embarassing his funeral must have been... same with the guy who was buggered to death by that stallion.
