Wow, so very many to choose from. In my younger days I was basically a juvenile delinquent, so I had lots of chances to fuck up.
I burned a nearly completed house under construction down when I was about 8. My friends and I were throwing lit rolls of toilet paper at each other. I thought it would be cool to set a “trap” in a pile debris. I soaked a roll in paint thinner and poured a paint thinner trail to another room. No one fell into the trap, so I lit it anyway. We DID try to put it out before we ran away, but weren’t successful. In the same town my brother and I managed to start a field fire that burned for a week, thanks to a bunch of lighter fluid and the idea that flamethrowers were fun.
I punched a hornet’s nest on a bet. I got paid, but it really wasn’t worth the five bucks. It seems that I made roughly 18 cents per sting.
My brother and I took my dad’s guns into the back yard to shoot. Didn’t occur to us that we had neghbors behind us; naturally they called the police, thinking someone was trying to kill them. When the police arrived we tried to convince them that we were shooting cap guns off. (This was pre-day-glo orange capguns) The officer asked to see the cap guns, so I took one from a drawer and pointed it at him, only to realize that he and his partner had drawn down on me and were screaming at me to drop it. It’s a wonder they didn’t cap me. IIRC the brand name of the cap gun was actually “Realistic.”
My friends and I used to hold BB-gun wars in the woods. The only safety requirement was sunglasses. Somehow none of us wound up blind.
When I was 14 I read a story about people who got a thrill from breaking into homes where people were sleeping. I tried it, and was emptying a change jar in the kitchen when the light came on and a man with a shotgun was there. I bolted out the way I came in (unlocked kitchen door) and decided that I was done with that particular thrill.
When I was 9 my brother and I constructed coffee can charity tins and went around collecting money for some local charity. We made about $50 and were caught only because my brother said something to our Mom about being “loaded”. Though not dangerous, this was by far the most embarrassing, since my mom made us go back to every house, apologize, and return the money.
Almost as embarrassing was the time my brother and I were caught drunk in church. Made worse by the fact that it was the wine for communion we were drinking. That was my last day as an altar boy. Other children might have been forgiven, but I’d already pushed my luck too many times. There’s somthing about tuening on the microphone and rapping Run DMC on the altar that really, really displeases your average Catholic priest.
I tried to pick up a rattlesnake by the tail, and was stopped only by my dad coming around the corner of the house and catching me.
Spent one night driving around with a paper bag full of bottle rockets, a bunch of beer, and a friend. We’d drive along and shoot the rockets out the windows at cows, cars, or people, all the while laughing uproariously at our subtle wit. As we’re whipping down a country road at about 70 miles an hour a spark fell into the paper bag, and the car filled with smoke and fire. My friend slammed on the brakes and barely made it to the side of the road while I’m screaming bloody murder as bottle rickets go off around my feet. We jumped out of the car, took cover and waited for the inevitable explosion, which didn’t come. When we went back to the car the passenger seat was basically gone, nothing but charred foam and springs. Explaining that it was my idea to his mom was not one of the high points in my life.
Take your pick.
