Naturally the doctor asks him what happened.

"Well, it was like this," said the man.

"I was having a quiet round of golf with my wife when she sliced her ball into a pasture of cows."

"We went to look for it and while I was rooting 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, I lifted the tail and yelled to my wife,
'Hey, this looks like yours!'"
