The comedian Gallagher had the right plan. He said to give everyone those cheap plastic plunger guns we all used when we were kids. Each plunger has a little flag on the end...some say "stupid" and others say "idiot" or "moron". Once a dumb driver accumulates enough of these on their rear quarter panel or trunk, a cop will see the accumulation, pull them over, and write them a ticket for being stupid!
