The Bernhard Langer Tree Shot
"In 1981 I became a world-famous golfer in a rather amusing way. I was playing in the Benson and Hedges International at Fulford. On the seventeenth hole I hit a nine iron to the green, pulled it left and it hit a big oak tree, to the left of the green. I heard the ball hit two or three times but did not see it come down. Seconds later the spectators started laughing and, sure enough, the ball was lodged in a little indentation in a branch about fifteen feet up! "
