Norman is 89 years old. He's played golf every day since his retirement over 20 years ago. One day he arrives home upset. "That's it," he tells his wife. "I'm giving up golf. My eyesight is so bad that once I hit the ball I can't see where the dang thing goes."

His wife sympathises and makes him a hot cup of tea. As they sit down she says, "Why don't you take my brother with you and give it one last try."

"That's a terrible idea" says Norman, "your brother's 102 years old. How could he help?"

"He may be 102 years old", says the wife, "but his eyesight is perfect."

Norman figured he'd give it a try So the next day he heads off to the golf course with his brother-in-law. He tees up, takes a mighty swing and squints down the fairway.

He turns to the brother-in-law and says, "Did you see the ball?"

"Of course I did!" replied the brother-in-law. "I have perfect eyesight".

"Where did it go?" says Norman.

"Where did what go? Do I know you?"
