Perhaps you've already read of the Horsely incident on Wonkette, but if not:
COLMES: "You had sex with animals?"
HORSLEY: "Absolutely. I was a fool. When you grow up on a farm in Georgia, your first girlfriend is a mule."
COLMES: "I'm not so sure that that is so."
HORSLEY: "You didn't grow up on a farm in Georgia, did you?"
COLMES: "Are you suggesting that everybody who grows up on a farm in Georgia has a mule as a girlfriend?"
HORSLEY: It has historically been the case. You people are so far removed from the reality...Welcome to domestic life on the farm...If it's warm and it's damp and it vibrates, you might in fact have sex with it."
