When I was in high school we "appropriated" a rather lifelike scarecrow figure from someone's front yard Halloween decorations. He was dressed in a pair of overalls with boots attached, a longsleeved shirt with gloves attached, and some kind of a head with a hat stitched on. He was then all nicely stuffed with crumpled newspapers. We tied a long rope around his neck and then drove around until we found a group of Trick-or-Treaters. We then sped by them in one of my buddies' car, let out a bloodcurdling scream and pushed Mr. Scarecrow out of the passenger side of the car and proceeded to drag him down the street. It was obvious that we scared the crap out of a bunch of little kids until we returned Mr. Scarecrow to his home, in somewhat worse shape than when he started out that night. Great fun!
