A manager was told by his doctor to take up some sport for exercise so he decided to play tennis. After a couple of weeks his secretary asked him how he was doing.
"It's going fine", the manager said, "When I'm on the court and I see the ball speeding towards me my brain immediately says: To the corner! Back hand! To the net! Smash! Go back!".
"Really? What happens then?", the girl asked enthusiastically.
"Then my body says, 'Who? Me? Don't talk nonsense!'"
