Chuck is 90 years old. He's played golf every day since his retirement 30 years ago.

One day he arrives home looking downcast. "That's it", he tells Sue. I'm giving up golf. My eyesight has got so bad...once I've hit the ball, I can't see where it went."

Sue sympathizes. As they sit down she says, "Why don't you take your brother Earle with you, and give it one more try".

"That's no good", sighs Chuck, "My brother Earle is a hundred and three. He can't help".

"He may be a hundred and three", says the wife, "but his eyesight is perfect".

So the next day Chuck heads off to the golf course with his brother Earle. He tees up, takes an almighty swing and squints down the fairway. He turns to Earle, "Did you see the ball?"

"Of course I did!", says the Earle. "I have perfect eyesight."

"Where did it go?", says Chuck.

"I don't remember", says Earle.
