Get a long board, nail a bunch a nails in it so they stick out onto the other side. Get a hook screw & nail that to the end of the board. Now find some long string about 10 to 20 feet, something tight so it won\’t break easily & tie it through the hook screw tightly. Once finished hide behind some bushes one night on a lonely dark street & wait until some car comes by, then quickly throw the board out under it\’s tires. Watch what happens, have a laugh, pull the string back, then run like hell!
