Baboons can take their place alongside odd animals found on a golf course, much to the surprise of England's Luke Donald.
The four-time Ryder Cup participant was lining up a shot during the second round at the Nedbank Golf Challenge in South Africa when he was surprised by the baboon.
Alerted by playing partner Shane Lowry, Donald jumped at the sight of the baboon before the animal moved on.
"Just before Luke played his shot...oh we've got a visitor," the commentator said during a replay of the incident.
It didn't seem to put Donald off, with the Englishman shooting a nine-under-par 63 to take a two-stroke lead after the second round at Sun City.
However overnight he gave up that lead in the final round to finish in third place.
