As a child, I always dreamt of being a dog. Consider for a moment these three reasons why anyone would choose to be a dog:
[li]You're able to scratch any part of yourself in public without fear. Everytime you get an itch, you can scratch it.
[li]You can harass other animals (cats, chickens, cows) for hours upon end and be pleased with yourself. Harass anything as a human and you'll get slapped with a lawsuit faster than a coffee-burn victim suing McDonald's.
[li]Taking a crap in someone's yard. Particularly in that annoying guy's yard next door.
