Once upon a time, there were a species of monkeys. These monkeys were as happy as monkeys could be. They were born, and lived typical monkey lives of eating, defecating, and fornicating. Of course, everything was not happy in monkey land, because some monkeys were a**holes.
It was as if the only thing these evil monkeys lived for were to screw with the other monkeys. Bad monkeys. Bad. Bad. Bad.
Overtime, the smart monkeys had more babies than their intellect-challenged brethren. Soon, there were a lot of smart monkeys.
WHAT ARE YOU GOING TO DO WITH ALL THOSE MONKEYS???
Evil monkeys (yes, some smart monkeys were evil) had a series of ideas: 1. All these monkeys have stuff; 2. Evil monkeys want that stuff; 3. How to get that stuff?; 4. Trick the other monkeys to voluntarily give you that stuff, AND work hard to give evil monkeys more, more, more.
How can you get all the other monkeys to work hard all their little monkey lives for the whims of evil monkeys?
