There was a room with 10 monkeys.
In the centre of the room hangs a bunch of bananas.
However, when a monkey reaches for a banana, water is sprayed at the remaining 9 monkeys. And often the monkey that reaches out for the banana gets whacked by the other 9.
Soon, one monkey is taken out, and another put in. Of course, the new monkey reached for the bananas, the others began to whack him furiously.
This let the new monkey know he's not supposed to go for the bananas.
Soon, another monkey is taken out and a new one placed in. Similarly the scenario reenacted. The new monkey got whack by 9 of the monkeys, of which included the not-so-new monkey that just joined in even though it didn't understand why the need to whack the new monkey.
Everything was repeated, and soon the room held 10 monkeys that whacks any monkey that tries to reach for the banana. No monkey ever knew the reason to why they should do it. They just do.
And everyday in my office I see a new monkey reaching for the banana. Sigh.
