Here's an interesting rule. If you address your ball on the tee and touch it causing it to fall off the tee there is no penalty. If you then take a swing and miss the ball (air shot) that is one stroke. If you again address the ball and accidentaly knock it off the tee again that is one stroke penalty and the ball must be replaced. The reason is that a ball on the tee is not in play until played. But after an air shot the ball is in play .
