When I was a kid and we went to my buddy's ranch, we'd pick up all the rotten oranges, and on the way back, we'd throw them at the windshields of cars in the incoming lane.
Haha, I'm smiling because of how recklessly dangerous that was. But man, what a fucking rush. We'd try to throw the really mushy ones into people's open windshields and shit. However, we got caught throwing shit so we started using airsoft guns, and trying to snipe the cars next to us on the highway.
