We used to raid the "dumpster" of nearly expired hostess products at the local hostess factory, and no bullshit fill the back of a jeep with twinkies and ho-hos and king dongs, then go drive on two lane roads and throw them out in front of oncoming traffic to try and get them to chase us.
I made the mistake of using my car as a paintball tank at an unofficial range. That stuff never came out of weather stripping on the windows and left streaks every time the windows rolled for years.
