A fellow was out on a golf course that bordered a farm playing a round of golf with his wife when they came to the tenth hole. The 10th hole at this course was a long par four with a dogleg to the right that happened to go around a barn. The husband set up to hit his drive but duffed it -- it went straight up -- and came down about 100 yards up the fairway. Not being able to reach the green from here, noticing that the green was directly behind the barn, he decided to hit his second shot through the barn.
He sent his wife over to the barn with instructions to open the doors at both ends. His wife did as asked, and waited in the barn as he pulled out his trusty three wood and took aim. He smashed a low screamer that went straight through the front door of the barn. Unfortunately the ball hit a post in the barn, ricocheted into the side of his wife's head, killing her instantly.
A year later, the fellow is out on the same course for the first time since the horrible accident. This time with one of the caddies from the club. At the 10th hole he once again he duffs his shot to the exact same place. He sighs.
The caddie says "Don't worry sir, whay don't I go over to that barn over there, open both doors, and you can hit your shot right through to the green?"
"No, no," says the man, "I can't do that"
"Why not?" asked the caddie.
"I tried that a year ago," he said, "...and it cost me three strokes".
