Air horn golf....

I reckon if they tried that on a few of the courses I have played they would be lucky to still be alive ! They would have imprints of club manufacturers on various parts of the body all painful.
 
Had it done to me once at my course was quite funny.

One course in Liverpool has a school near it (could even be just behind the fence)so I've had the odd expletive and "encouraging" words at the top of my backswing on the odd occasion!

If they did it once or twice I'd find it amusing but after that I'd do what the guy at the end did (but I'd probably top it)
 
Not right but it is very funny, especially when the guy tees up and takes aim .... you can almost see the red mist!

Mates missus once gave it a full on blast of the horn while waiting at the traffic lights directly behind our 10th tee when one of our 4 ball was just at the top of this backswing. He topped it, we all turned to see her driving off in fits and we just rolled about laughing too. Proper comedy moment, the guys reaction was classic, full on toys out of pram complete with shouting, swearing etc which just made it even funnier.
