I suppose for those "off' days, it would come in handy, but not sure if I want to be seen in public spraying poop and then picking it up. I think I'd have to mess with people and tell them I dry it and make crafts...
Reminds me of this guy on Americas Inventors last week. He invented a popper-scooper that you actually have to hold under fido's butt as he's going so the poop is deposited into the poop cup. Then you close the lid, and pull out the disposable cup and dispose of it! Sounds good you think? Only if you're into chasing fido around while he's looking for the perfect spot to go, and once your dizzy from the endless circling that fido does before making the deposit, hopefully you aim the pole/cup under his butt and not your own!
Ahhhh well...some people have waaaay too much time on their hands!
