When I was 14, and was putting on my shoes, I was pulling them up at an angle because of how I was sitting in a chair and when I finally got my shoes on, my elbow was under the chair handle and without thinking, I extended that arm away from my body after getting my shoe on at a pretty fast speed, and my arm bent around the handle and I broke my arm on the spot....

I have done a lot of stupid things haha dunno probably when i ended up pelting myself in the head with a golf ball, now that was unintentional painful and stupid.

Probably falling out of my tree stand when I was hunting.

I was walking down the street texting and walked into a lamp post hurt like a mofo

This happened 3 days before tennis tryouts my for my Junior year.

I was playing tennis with my friends and was showing off a bit to much with sliding and tweeners (hitting the ball through my legs) and ended up fracturing my ankle. I was missed the first month of competitive play. Came back and climbed the ladder to #2 singles and #1 doubles. I should have messed up my ankle more often.

One time when i was drunk i spilt acid on my skin and it burnt my skin and now i have white splotches in certain places on my skin.

Well mine would be cutting my self with a butter knife thats the dumbest way i can think of injuring myself

A a teenager I rode my skateboard down my big hill and as soon as I get in the road I fall and got scraped up. Someone was jogging and seen me fall, they continued on jogging lol.

The dumbest way I injured myself was by putting a spray paint can in the fire and well me and my buddy's were waiting for it to explode and finally it does and it shoots right out and hit's me in the knee. Never doing that again

One time I used my front brakes on a new bike going down a hill and messed my hand up pretty bad.

Another time a larger kid feel on my wrist in football and broke it.
