Anyone who's ever watched golf knows that the fans who shout "get in the hole" the moment a tee shot has been taken are the worst people in the world.
So it was a joy to see one such person brilliantly shot down when he made himself heard during Rory McIlroy's win at the Irish Open.
It was slightly unclear whether the voice shooting down the over-enthusiastic fan was McIlroy's caddie JP Fitzgerald or just another spectator who knew better.
Either way, it met with firm approval.
The punishment for shouting "get in the hole" really ought to be a lifetime ban - or possibly a lifetime membership at Muirfield.
