Two golfing friends were about to tee off, when one fellow noticed that
his partner had but one golf ball.

"Don't you have at least one other ball?", he asked.

"Nope, I only need one ball."

"Are you sure? What happens if you lose that one?"

"This is a very special golf ball. You can't lose it, so I don't need
another one."

"What do you mean you can't lose it! What happens if you slice your shot
and the ball goes in the lake?"

"That's okay, this special golf ball senses when it's under water and it
puts out a steam of bubbles. I'll be able to retrieve it. You can't lose
this ball"

"Well what happens if you hit it into the long rough?"

"No problem, you see, this ball can detect the long grass and it sends up
puffs of fluorescent smoke. I'll be able to see it easily. You can't lose
this ball"

Exasperated, the friend asks, "Okay. Let's say our game goes late, the sun
goes down, and you hit your ball deep into the trees and it gets lost
among the bushes and shrubs?. What are you going to do then?"

"That's okay too. You see, this special ball can sense the darkness and it
makes a beeping sound. I'll be able to get it back - no problem."

Finally satisfied that he needs only the one amazing golf ball, the friend
asks, "Hey, where did you get a golf ball like that anyway?"

"I found it."
