While driving down a dirt road in my pickup truck in a rural agricultural part of Iowa with my pet donkey in the back, I discovered that I had a flat tire. I got out of my truck and had the donkey stick its head under the bumper to lift the truck.

A passing farmer asked, "Hey, that's a pretty clever trick. How did you teach your donkey to lift the truck?"

I replied, "It's a simple matter of the breed; this is a jack ass."
