The Poo Collectors

You ever see those people taking their dog out for a walk, the dog poos, and the person picks it up with a plastic bag? I want to know what they're doing with that poo. Where does that poo go? And what if the dog has diahrrea? Do the poo collectors still pick it up? I need to know what they're doing with that poo. It must be of some value. Perhaps there is a black market for dog doo. I've walked past a few of the poo collectors in the act of collecting the poo. They try to pick it up as soon as possible and avoid eye contact as if they think I'm going to try to steal it. And another thing, why do they almost always use a clear plastic bag? Its like they want people to see their dog's poo. Like they're proud of it. "You think thats a big piece o poo. Look what I got. Mine has a peanut in it." The poo collectors. It baffles me. They must know something I don't. I gotta get some of the action. This could be my big break...
