Even the brightest of us are not immune to doing dumb things. Call it a brain fart, a fog in the decision-making department, a moment of irrational impulse, or a ‘whatever happens, happens’-type of mindset where for a fraction of second, everything kinda makes sense, even the things that normally don’t.

So when someone asked “What is the dumbest thing you’ve ever done for absolutely no reason?” unbeknownst to them, Pandora's box of some entertaining stories was opened. Think of putting gum in your eye just because your dad told not to do that at whatever cost, or opening the door of a moving car just because you wondered what it’d feel like.

Basically, below is one hell of a ride, both hilarious and very relatable. Psst! After you’re done, be sure to check out our previous post on the dumbest things that pretty smart people have done.

40 Times People Did Something So Dumb For Absolutely No Reason And Shared It In This Thread Someone asked me what time it was and I lifted and rotated my wrist so I could look at my watch. I was holding an iced tea and just poured the whole thing into my lap.

I wasn’t wearing a watch.

I didn’t even own a watch. Never have.

40 Times People Did Something So Dumb For Absolutely No Reason And Shared It In This Thread I jumped up and (successfully) bit the string that is used to pull the attic door down. It had a metal bead on it... Immediately after I remember thinking “holy s**t I actually got it in my mouth and broke the string”. Then I realized the string was still there, but half my front tooth wasn’t.

As the best man at my wedding said “the attic string went fishing for idiots and caught one”

40 Times People Did Something So Dumb For Absolutely No Reason And Shared It In This Thread I chopped an aerosol paint can in half with an axe.

40 Times People Did Something So Dumb For Absolutely No Reason And Shared It In This Thread We were driving to a restaurant and wanted to see how long the wait was. My dad handed me the phone book and asked me to look up the number. I, for whatever reason, thought he said “get rid of this”. So I opened the window and chucked the phone book while we were going 70 MPH down the highway.

That was over ten years ago, I still get s**t for it.

40 Times People Did Something So Dumb For Absolutely No Reason And Shared It In This Thread You know those old cigarette lighters in cars? Nobody in my immediate family smokes, and when I was younger, I pressed it in and it popped out.

I pulled it out to inspect - it was just grey coils - it didn't look red hot or anything. So I tested that sucker the best way I knew how. I stuck it to my tongue.

40 Times People Did Something So Dumb For Absolutely No Reason And Shared It In This Thread Microwaved a pen for two minutes in the workplace microwave. To this day I do not know why I did that. Update: I'm still at the same job. The pen was a Frixion Pilot. When the ink smoke cleared and my senses came back to me, I quickly ran across the street to Lowe's and bought the same exact microwave to replace it with. I was never caught.

Remember the Leave it to Beaver where Beaver does that with a fence at the park? My Mom and sisters and I were sitting around the kitchen table one time talking about that episode. We didn't realize that my young nephew must have been listening until he stuck his head through the spindles of a captain's chair. Sure enough, he couldn't pull it back out. The bad thing was that we were laughing so hard none of us made a move to help him for awhile. Exquisite timing!

My God! I have just had a flashback! My mum and dad stopped to ask for directions. I was in the back seat. While the guy was giving the directions, standing side-on to the car and pointing at the map, I reached in his pocket and took out his wallet. We drove on and I told my parents. Natch, they were horrified. They turned around and went back and found the man still walking along the street. That would have been embarrassing conversation! I must have been about 6 at the time (I'm 64 now) and as I say, this item just gave me bang! a flashback. Sorry, man. Sorry, mum and dad.

40 Times People Did Something So Dumb For Absolutely No Reason And Shared It In This Thread When I was about 7 or 8 I decided to hold my breath as long as I could ... with milk in my mouth while staring absentmindedly out the window. Naturally I spit the milk all over said window when I lost my breath. I don’t know what I learned. I don’t know what I gained from doing this. I don’t know my motivation. I laugh when I remember it because... what the f**k was even happening in my mind. If anyone is wondering - my aunt saw the milk explosion happen and was like “why did you do that?!!!!” I don’t even know what I said. I just cleaned it up.

This is really dark, but I had a friend who once tried to commit suicide with a rope in a tree. The rope was too long. She jumped and wound up on the ground. Fortunately, she figured if she couldn't even kill herself correctly, she probably shouldn't be making life or death decisions. She got herself the help she needed.
