What is your worst stupid idea?

Using a chemical hair-removal cream in high school just because it gave me horrible nightmares about weird hair growth for a while.

Stuffing the powder from a dozen fireworks and two shotgun shells into the metal barrel of a toy pirate gun, ramming it home with a heavy bolt as a projectile, holding the miniature cannon in my hand, and lighting a fuse stuck in the whole thing. It had the kick of an 8 gauge shotgun in the form of a handgun and the bolt wound up embedded in the ironwood door of my best friend’s dad’s machine shop. I’m lucky I didn’t blow myself up.

I had a raw spot on my privates, from a bit of the old in and out.
I poured some alcohol on it, hoping to disinfect it. Pain like no torture ever achieved.
I then poured water over it. Same result.
People in my apartment complex talked for weeks about the scream they heard.

Ask me on my death bed and I’ll probably have enough stupid things done to write a trilogy.

hmmmm… stupidest so far…

make nitro glycerin and napalm and accidentally tossing them into the nearby sink hole dump (I mixed up the boxes).

Falling in love.

For whatever reason I plucked some leaves off a plant that was growing up a tree and was rubbing them on myself, in my armpits, neck, arms, while I was yelling, “I’m taking a shower!”. My dad kept telling me “That’s poison oak!” In all my 10 year old knowledge, I told him it wasn’t, he didn’t know what he was talking about, etc. I’ll just say, poison oak isn’t cool in your armpits.

Extending the zip line off the tree fort with ½” sisal rope. It snapped and I fell 30’ to the ground and the 20 lb. barn pulley we used landed right next to my head. That hurt real bad.

When I was around 14/15, you know…dumb! I stuck my finger up a light fitting, just out of morbid curiosity…...that’s my excuse & by gum i’m sticking to it!
Well, unsuprisingly it turned out to be a shocking error of judgement. I went all “Scooby Doo villain” for a minute. Skeleton showing, hair standing on end, you know the look.
I have to say however that immediately the shockwave ceased I felt ever so slightly turned on, weird dat! So yeah, that would be my stupidest prank. We live & learn ;¬}

The bird-feeder needed refilling, and after I’d done it I couldn’t get it back up, being of the… shall we say ‘short’ persuasion. I had the brilliant idea of tying a rock onto the end of the rope to act as a weight, so that I could sling the rope over the branch and hoist the feeder back up into the tree. There was much rope twirling like in the old rodeos old on t.v, at one point I let go of the rope, forgot to give slack so the rock hit the end of the rope and came whizzing back at my head. You’d think I’d learn, but nope – I kept trying – at least until the rock came loose and forced me to run away or get pole-axed, my Dad couldn’t stop laughing as he stayed well clear and I got chased by a bouncing rock.
