I got one for you all. Me and another young one had a shot gun shell. Being young and stupid we dug out the primer and hit that with a hammer. Boy that was one loud report. My buddy's parents thought we shot a gun. We never pulled that trick again.
Or my dads shotgun we snuck out of the house. Dad had a 12 gauge single shot shot gun. It broke down into three pieces, Three of us broke it down and snuck it out of the house. Took it into the woods a long way from the house, put it back together. None of us wanted to shoot it from out shoulders so we butted it up to a tree. Loaded it up and pulled the trigger. It was very loud and it sunk into that tree about an inch. We all giggled about it but I was the one the one that got their ass beat from taking it out side and shooting it. Learned a good lesson from that beating. Don't mess with dads gear. I was 10 maybe. Never ever messed with dads gear again. Too bad you can't spank your kids anymore.
