Start with a cage containing five monkeys. Inside the cage, hang a banana on a string from the ceiling. Place a set of stairs under the banana. Before long a monkey will go up the stairs and reach for the banana. As soon as he touches the stairs, all the other monkeys are sprayed with icy cold water which is quite unpleasant for monkeys. When a second monkey make an attempt to reach the banana, again all the other monkeys are sprayed with icy cold water. A third monkey going for the stairs is prevented from doing so by the others. From that point on no monkey dares attempt to reach the banana. The cold water is put away and one monkey is removed from the cage and replaced with a new one. The new monkey sees the banana and attempts to climb the stairs. To his shock, all of the other monkeys beat the crap out of him. After a second attempt followed by the same punishment, he no longer attempts to climb the stairs. A second of the original monkeys is removed and replaced with a new one. The newscomer goes for the stairs and is atttacked with the previous newcomer enthusiastically taking part in the discilinary action. One by one replace the third, fourth, and fifth monkeys in the same manner until there are no monkeys left in the cage who have ever been doused with icy cold water. But any newcomer who attempts to climb the stairs to reach the banana will be attacked by all the others. Why? Because in their minds it has always been that way. MORAL OF STORY: Every now and then, most or all of the monkeys should be replaced at the same time.
