As a sociological experiment 10 monkeys were placed in a large cage. High up at the top of the cage, beyond the reach of the monkeys, were a bunch of bananas. Underneath the bananas was a ladder leading to the bananas.
The monkeys hadn't been fed for 12 hours and were extremely hungy. The monkeys immediately spot the bananas and the strongest begins to climb the ladder. As he does, however, a slight electric shock keeps him from ascending the ladder. At the same time that the monkey climbing the ladder gets a shock, the other monkeys on the floor are sprayed with water.
