Yup, worth a go. Try it next time you play a corporate golf day...
Here are some other tricks you might want to try whilst you are at it -
If opponent is not watching stand on their ball and push it to the ground so unplayable and then keep walking.
When no-one is watching pick up the opponent's ball and spit on it and put it back for them to play their next shot.
When no-one is watching try rubbing a pencil rubber (or some dry soap) on the face of their golf clubs.
When no-one is watching you might try to put (or a driver if a long shot) in to your opponent's wife...
...if that doesn't work have a go using a 9 iron or pitching wedge over the clubhouse on to the roof/bonnet/boot of your opponents car in the carpark.
Good luck and tell me which hospital you end up in and I will send some whisky to help you recover.
