A man staggers into an emergency room with two black eyes. Naturally the doctor asks him what happened.

"Well, it was like this," says the man. "I was having a quiet round of golf with my wife, when at a difficult hole, she sliced her ball into a cow pasture. We went to look for it, and while I was searching around I noticed one of the cows had something white at its rear end. I walked over and lifted up the tail, and sure enough, there was my wife's golf ball stuck right in the middle of the cow's butt. That's when I made my mistake."

"What did you do?" asks the doctor.

"Well, still holding the cow's tail up, I yelled to my wife, 'Hey, this looks like yours!'"
