Arthur is 81 years old.
He's played golf every day since his retirement 16 years ago. One day
he arrives home looking downcast.
"That's it," he tells his wife. "I'm giving up golf. My eyesight has
got so bad. Once I've hit the ball, I can't see where it went."
His wife sympathizes, and suggests, "Why
don't you take my brother with you, and give it one more try."
"That's no good," sighs Arthur. "Your brother is 93years old. He can't
help."
"He may be a ninety three," says the wife, "but his eyesight is
perfect."
So the next day, Arthur heads off to the golf course with his
brother-in-law. He tees up, takes an almighty swing, and squints down
the fairway.
He turns to the brother-in-law. "Did you see the ball?"
"Of course I did!", says the brother-in-law. "I have perfect eyesight."
"Well, where did it go?" asks Arthur.
"Can't remember."
