(1) Each golfer receives 2 mulligans, to be taken anywhere except in a sand trap or on the green, for every nine holes played without penalty, unless the golfer needs more.
(2) Whenever not on the green or in a sand trap the golfer may move the ball 2 club head lengths, unless really in trouble in which case the golfer may move the ball two club lengths, in any direction.
(3) A ball hitting a tree shall be deemed not to have hit the tree. Hitting a tree is simply bad luck and has no place in a scientific game. The player should estimate the distance the ball would have travelled if it had not hit the tree and play the ball from that point. Preferably atop a firm tuft of grass.
(4) There shall be no such thing as a lost ball. The missing ball is somewhere on or near the course and will eventually be found and pocketed by someone else. Therefore it becomes a stolen ball. You should not compound the felony by charging yourself with a penalty stroke.
(5) If a putt passes over a hole without dropping, it is deemed to have dropped. The law of gravity holds that any object attempting to maintain a position in atmosphere without support must drop. The laws of gravity supercede the laws of golf.
(6) The same thing holds for a ball that stops at the brink of a hole and hangs there, defying gravity. You cannot defy the law! Same rule applies to a ball that rims a cup. A ball moving sideways defies the law of physics.
