WATCH: Did you hear the one about the monkey, the motorbike and the men?
Monkeys have a reputation as being playful, fun loving, happy creatures.
But in this video an ape revealed his darker side.
This footage shows two men in Chachoengsao, Thailand trying to mount a motorbike but being blocked at every attempt by a mischievous monkey.
The men and the monkey then became engaged in harmless play-fighting but the jolly atmosphere didn't last long, and soon a real fight breaks out.
Both man and monkey are not in the mood to be trifled with, and both launch attacks on each other.
The row kicked off when the monkey provocatively peed on the motorbike, damaging the seat.
Retaliation by the men comes swiftly in the form of a flying shoe.
However, rather than retreating, the monkey responds by charging at one of the men.
It makes for rather unpleasant viewing and teaches us a valuable lesson - Monkeys may look cute and innocent but they have a serious diva streak.
