"A man walks into an emergency room with two black eyes and a broken nose.
The doctor asks him what happened.
'Well,' says the man, 'I was having a nice round of golf with my wife. She sliced her ball into a pasture of cows. We went to look for it, and while I was rooting around, I noticed that one of the cows had something protruding from its rear end. Sure enough, when it lifted its tail, there was my wife's golf ball.'
'And?' asked the doctor.
'Well,' the man said, 'that's when I lifted the cow's tail, pointed, and yelled to the missus, 'Hey, honey - this one here looks like yours!''"
