Back in the days when the great plains were ruled by dinosaurs, the local Tyrannosaurus came to you and your dinosaur friends with a proposition you couldn't refuse: help eliminate the neighboring Tyrannosaurus to open up a new food supply, and you and your friends won't get eaten. Your brain is the size of a walnut, so this 'not getting eaten' bit sounded like a pretty good idea. Little did you realize that the neighboring Tyrannosaurus had the same idea. Who will be the next Dino-Czar?
