Years ago I was working construction on a house and an iron clamp (around 2 or three pounds) under tension with a chain snapped and flew towards me and hit me in the forehead hard enough it spun me ass over tea kettle off of a scaffold where I belly flopped onto concrete about 6 or 7 feet down. I woke up about ten minutes later with paramedics around me laying in a pool of blood. I was air lifted by helicopter to the city around 80 miles away.

I still have a nice 2 inch scar on my head from where it hit, but thankfully I have a nice thick skull and I didn’t get any brian dabblage :)

I have 3 plates 16 screws and a plastic eye socket I got when I was jumped with brass knuckles

Earlier today I tried to swat a fly with my car door, but since I was looking down at the fly I only managed to slam that door into my head with all my strength, stunning me for several seconds

Metal pole

Also hardest thing I bit. I dented it. My teeth did not chip or crack at all

I sometimes wonder if I am part Idiot Anime Protagonist

Once, when I was a kid (albeit old enough to know better) I was playing underneath a tall warehouse-style shelf. I could just stand up underneath it, so what do I decide to do? Jump as hard as I can, of course!

I’m not sure how I didn’t end up in hospital on that one.

When I was really little, my uncle was pulling me behind a motorcycle on one of those plastic kids sleds and I rolled off face first into a pine tree.

Or maybe it was a couple years later when I got in a fight in line to go to the library and a kid grabbed the back of my head and smashed my temple onto the corner of a Formica countertop.

Or it could be when I caught the biggest guy in my Army unit jerking it and couldn’t keep my mouth shut and he did his level best to break my jaw. He must’ve had 6" and 100 lbs on me. Fortunately my head got in the way and I had to get stitches in my forehead from the punch and in the back of my head from the doorway he knocked my head into.

There were some other contenders, but those three all involved stitches and none of the others did.

I suppose running down the stairs when I was 5 or 6. Look I was really excited to use those stickers. Tumbled head over heels down the basement stairs and struck the top of my head on the support beam at the bottom. Ended up getting stitches, a bear stuffy, and topical cocaine so obviously I came out ahead

When I was two or three I hit my head on the corner of a table in a post office and had a huge gash above my eyebrow. It had to be stitched and for some reason the doctor didn’t allow my mom to hold my hand. She still kicks herself for not insisting enough. I don’t remember it at all apart from the scar.

Not the most dramatic, but when I was really little I remember play fighting with my brothers, and falling backwards off the bed and hitting my head against a dresser.

There was no wound or anything but I remember seeing all kinds of fucked up colors at the moment of impact. Despite being a huge crybaby, I’m pretty sure I didn’t cry or freak out, I was just extremely fatigued.

I wonder if we should have gone to the doctor. I don’t think you’re supposed to see TV static and rainbow vomit when you bump your head.

When I was seven or eight, my siblings and I were playing a game where we put the clothes hangers with the clippers on the ceiling fan, turned it on, and see where they flung. One of them headshotted right into me.

First and last snowboard lesson. Long time ago. Never again.

When I was probably somewhere around 10-12, I was walking backward and turned around right into a wall. Fell onto my back, then ran to the bathroom and threw up 6-7 times.

probably a hit i took during football that i mysteriously lost memory of

One time I randomly decided to jump and touch the ceiling while standing in a doorway… I thought I broke my neck for a minute

Diamond, technically. It’s not the hardest thing in existence but probably the hardest my head has made contact with.
