Golfing with the wife

"Well, I was playing golf with my wife. I'd been having a great game but unfortunately she wasn't. On the 15th tee I hit a beautiful shot, 270 yards straight down the fairway. My wife steps up and hits a tremendous slice that leaves the course and lands in the pasture out of bounds. We both went looking for the ball and just as we were about to give up I spotted a glint of white coming from a cow's behind, just under its tail. I lifted the tail to make sure and then called to my wife saying 'Here, honey, this looks like yours'. That's the last thing I remember."
