Olivia, If you collect enough of them you can possibly put them in a little box on a post on your street with a sign. "Please use these to pick up your dog's S**T".
See, now you have become a community activist and will be written up in your local newspaper. Then the local TV crew will arrive. This, of course, will lead to an interview on the "Today" show. Which will in turn, get you an invitation to a White House party. Where you will be identified as an uninvited guest and flown to a foreign country to be questioned by some nonexistant government agency. Under the effects of the drugs used to get you to tell the "TRUTH", you will be instructed to remember being abducted by an alien space ship and given an anal probe. You will then be deposited back in your own neighborhood in time to sign a contract to be a guest on Snagg's next "Fear and Loathing" program. This will in turn lead to NBC offering you a contract to host a reality show in the time slot being vacated by Leno. I wish, for your sake that this process could be shortened, but fear that is impossible
