Once upon a time, back when the dinosaurs still roamed the Earth, there was a man named Hookey Bookus, but, to protect his identity, we will call him Fred. Fred wanted a companion--a pet that would hang out with him, but this was before men had pets. He wasn't sure what animal to get--he thought about getting a tyrannosaurus rex, but decided that a t-rex would not make a good pet, and would probably eat him for dinner. Then he considered a mastadon, but the mastadon was too big to fit into the cave. He bought a cage thinking he might get a birdasaur (early man did not realize that birdasaurs were evil), but the dinosaur birds of the era were too big for the cage. Then he thought about a saber tooth tiger, but cats were too picky about their food for Fred's taste! Finally, he found a wolfasaur, and the wolfasaur became a perfect pet, and as time went on, evolved into a dog. Of course, we dogs are the ones in charge, but we let the humans think we are their pets. It keeps them happy--it takes so little to keep the humans happy.
