You know what really puts us off our stride when we're out on the golf course? Mongooses! Those naughty little critters have no respect for boundaries and are forever running across the green when we're about to take a shot.
Not convinced this kind of thing really happens? Just take a look at the above footage from the Nedbank Golf Challenge in South Africa, in which a family of banded mongooses from a nearby game reserve take a short cut through the middle of a match.
OK, we know the quality of this video is a bit rubbish - particularly as it's slightly obstructed by the reflection of the fella recording the sports news off his TV. But you get the idea, don't you?
Mind you, it's not just the mongooses who've been causing havoc at Nedbank: it seems they've been having terrible trouble with the baboons, too...
