A man walks into a country club, and asks to play a round of golf. The man behind the counter suggests he try one of their brand new mechanical caddies. The guy had just gotten his paycheck, so he had money to burn, he figured "what the hell".
He took the caddy out and it was great, it would tell him what club to use, what was wrong with his swing, and what direction his putts would break and how much. The man gets done, and shoots the best round of his life.
A month later he comes back and asks for one of the caddies. The manager replies, "I'm sorry, but we had to get rid of them." The man a little confused asks, "Why did you get rid of them, they were great." The manager explained that they were made out of metal, so when the sun reflected off of them, it blinded the other golfers.
Still confused, the man adds, "Well, why didn't you just paint them black?"
The manager replies "Well, we tried that, but then 2 of them didn't show up for work, and the others robbed the clubhouse."
