Let me see.....a rotting carcass, a defecating cow and a hyena walk into a bar....the rotting carcass says, this round's on you guys. I forgot my wallet.
Easy, as Wigglee said, the cow. It can pull the plow, yank the family vehicle out if the ditch or down to the garage, fertilize the garden, cut the grass, keep us warm and feed the family. You just don't see the broader picture.
