How to Play Golf
For several years a lawyer and a doctor had regularly played golf together. They were evenly matched, and there was a keen sense of rivalry. Then one spring the lawyers game suddenly improved so much that the doctor was losing regularly. The doctors efforts to improve his own game were unsuccessful, but finally he came up with an idea. At a bookstore he picked out three how-to-play golf texts, and sent them to the lawyer for a birthday present.
It wasnt long before they were evenly matched again.
