Tom addressed the ball and took a magnificent swing but somehow, something went wrong and a horrible slice resulted. The ball went onto the adjoining fairway and hit a man full force. He dropped!
Tom and his partner ran up to the stricken victim who lay, quite unconscious, with the ball between his feet. "Good heavens" said Tom, "what shall I do?"
"Don't move him" said his playing partner, "if we leave him here he becomes an immovable obstruction and you can either play the ball as it lies or drop it two club lengths away."
