I was seven years old and I decided it would be a good idea to put my arm on a shiny part of the push mower after I had finished mowing the backyard...

Another one... putting my finger into my laptop's cooling fan, which I "modified" by removing the protective steel grating so the air flows easier.

Few years back I wrote my own name with wrong spelling in a class test and the examiner corrected it.

Out of boredom? Imagining myself as a swordmaster and using a badminton racket as a blade. Ended up hitting my leg.
Second one... I tried drifting with a bicycle and accidently pressed the wrong brake. I was supposed to use the rear brake to make the rear wheel lock up, but I used the front brake and fell off. Fortunately the bicycle is fine.

@MrSilverWolf Tis indeed

@JacobHardy64 and is that a SkyLane in your profile picture?

I did that to all the computers that I logged in to. (I did it when I was done with what ever I was doing)@JacobHardy64

@JacobHardy64 I've always wanted to do that to my schools computers, I did take the goggle, and Crome opening windows and made them as small as I could get them and hid them behind the app dock and behind the thing were if you click it brings you back to the main page of the computer and there was hardly any to click on to drag it back out again so it would just be this viscous cycle and no one knew who did it lol

Lol @UnknownNate

I fixed it by the way @Sirstupid "you didn't see anything"

Always blame it on the autocorrect 👍🏻

I know, stupid autocorrect. @Sirstupid

"A step to fart" @MrSilverWolf

And when I was in fifth grade about 90% of the class had pea shooters made from mechanical pencils and agian one of my friends took it one step to far and made a cross bow out of a normal pencil with a rubber band for the string and shot one of the really annoying class mates at school and you can guess what happened then, but when the teacher four out he said "if you turn them in you won't get in trouble but if we're the one that hit the kid with the little piece graphite you will" so he made us fill out a sheet saying who we thought it was so the friend convinced everyone to blame it on another annoying class mate and we did expect that class mate (obviously) and he did actually get in trouble for it although he didn't do it lol

Oh my that's talent @MrSilverWolf

Lol, my friend did that, then he took it one step to far, he took a red sharpie and colored it around the staple and when around the school pretending that he had a staple deep in his hand, the best part, he almost made one of the teachers pass out, and another one just laughed at them and said "nope" @JacobHardy64

bows @Sirstupid

👏🏽👏🏽👏🏽@JacobHardy64

I stapled my finger once @MrSilverWolf

Lol, my excuse is "Sorry I had other and better things to do" and the teachers will go "oh really like what" and I'll respond "I had to build my An-2" (or whatever ever the model I was building at the time they asked me this) @Sirstupid

Also, best excuse for not doing homework: Sorry, I couldn't check what my homework was because my computer got adware from Sweden. @MrSilverWolf

I should lol @Sirstupid

Say that next time. @MrSilverWolf

Lol @Sirstupid

Grow organic drones. @MrSilverWolf
