A video shows the little capuchin attacking the roof of the bar with the foot-long kitchen knife after chasing after drinkers Customers at a bar were given an almighty fright when a drunk monkey snatched a kitchen knife and started chasing them after downing leftover rum. The little capuchin - a breed known for their temper - apparently turned aggressive after helping itself to dregs of rum in the bar. Picking up the foot-long blade, the animal reportedly set about terrorising punters at the bar in Paraiba, Brazil.
