I rather not say these neither.... but I will anyway. Just keep in mind that I was never the "head master" of these stupidity, but young and stupid enough to ride along for it.....
My buddy put some dog poop in a really nice looking box and left it in the middle of the road. Motorist had stopped and picked it up, then see it get thrown out of the window.
We also used to throw beer bottles in the middle of the street. I'm talking about a case of empty beer bottle....if not more than a case.
We've also placed heavy firecrackers inside a beer bottle and let it go off. Nobody got hurt but daaaaymmm..... that is so stupid!
