Put eight monkeys in a room. In the middle of the room is a ladder, leading to a bunch of bananas hanging from a hook on the ceiling. Each time a monkey tries to climb the ladder, all the other monkeys are sprayed with ice water, which makes them miserable.
One of the original monkeys is then removed, and a new monkey is put in the room. Seeing the bananas and the ladder, he wonders why none of the other monkeys are doing the obvious, but, undaunted, he immediately begins to climb the ladder. All the other monkeys fall upon him and beat him silly. He has no idea why.
