Stupidest thing you've ever done?

What's the stupidest thing you've ever done?

For me, it was probably cutting my finger with scissors. I should have gotten stitches for it. Sometimes, if something hits it, it hurts like crap!

Losing my underwear on a beach..

When I used to play in a band, after a gig we went to a beach (It was about 4 am). We were drunk, and swimming in underwear. I don't know how, but I've lost mine, and couldn't find it, and my friend took my other clothes and hid them, so i had to walk around butt-naked to find it, and there were lots of people there... and this girl I liked was there... and damn... that was really stupid...

Losing my cellphone in a community centre.

Usually I always make sure to have my essential tools alongside me whenever I go somewhere, but a few years I ago I somehow hadn't realized that my phone dropped or slipped out of my pocket when I volunteered at the community pool swimming competition. I had my wallet and keys with me in my other pocket, but was shocked to only realize my phone was gone once I got home.

I actually feared the worst if it had fallen into the pool (though I actually didn't get into the water). I went back to find it, but couldn't find it anywhere. Fortunately, a kind woman found it and had called my dad's number minutes before I got home again. Managed to get my phone back that day, but dang - nearly lost it just due to being careless!

Another one - running up the stairs at my uncle's place and falling face first on the top step. Had to get minor stitches for my eyebrow soon after. X.X

Punching my brother in the soloplex (if thats how u spell it). It's the place right in the center of ur chest. If you punch hard enough it knocks the wind out of you and potentially kill you. -.- It was by accident and i felt soooooo bad... He was literally lying on the floor dying for oxygen..... I still regret doing it, even when i didnt intend too. thats the most stupidest thing i did ever in my life.

Pretended that my dog was a human for a day. I must've been really bored because I felt really stupid after it.

Back in my younger years, I would play baseball in my backyard(Either by myself or with a couple friends). On that day though, I chased the ground ball. I jumped off the little hill, but I must of forgotten how to land or something, because I landed in a weird way where I kinda kneed my wrist which broke it. I'd have to say that was pretty stupid on my part. Other then that, I don't think I have done anything stupid.
