Do you know why I

Do you know why I keep a dog? It's because of the way his eyes get all big and round when I wave his plush soccer ball around. To get a person to look that excited, you'd have to be waving a Porsche in the air, but the velvety toy does the dog just as well. And not only that -- by the second or third time someone gave you a Porsche, your eyes wouldn't get so wide. It'd be old hat. But for the dog, each and every brandishment of the fuzzy orb produces the same wondrous glee. As long as you keep the plush toys and the bones coming, they live in magic.
