Watching Animal Planet, in the broadcast the lady says that now will teach the male and female monkeys simple action.

Takes a stone and nuts, breaks the shell with a stone and eats the fruit. Repeat the procedure. Gives a stone and nuts to the male. He did not understand anything and tried to scratch his shell with his teeth. Obviously nothing goes. The barley gives a stone and a female nuts. She quickly repeated the action by breaking the shell with a stone. The maid again gives the same things to the male, he thought and gave to the female. The obvious thing broke up and ate. The barley again gives the nuts and the stone, the one again gives to the female, the other breaks the nuts and at the same moment the male catches out the insides with a satisfying moustache and eats them.
