After extensive research we have uncovered that cheating at golf is pervasive at almost all clubs in the UK. Tut-tut. For the honest players out there, we have the solution they need to thwart a cheat. It's called Incred-a-ball and here is how it works: inside Incred-a-ball there is a spinning gyro. This is activated by a remote control. When you press the remote control, Incred-a-ball spins around in all directions as if possessed. Take Incred-a-Ball with you in your caddy and when you suspect your fellow player of reporting fewer strokes or faking his handicap, swap his ball for Incred-a-ball to teach him a lesson.

DANGER: if he discovers you are the prankster he may approach you with his nine-iron aloft. If this happens retreat to the undergrowth until he has calmed down.
