LOL! That is pretty funny!

It's quite funny. But it isn't a monkey. It's a gibbon, which is the
smallest of the apes. The video isn't clear and it took me a few
minutes but it is a gibbon. The lack of a tail is a good clue. I think
those cubs are big enough to kill him (or her) if the gibbon gets
unlucky. I would wager, although I would not give long odds, that this
was in some sort of captive situation and the animals knew each other.
