Name change for this thread, ahem!
3 things spring to mind (although probably many more!)
First one when I was about 14 and on holiday I ran my calves over whilst riding a quad bike and simultaneously got my head stuck through a fence. Was trying to turn a corner, did not lean into it enough, carried on straight, panicked as the fence loomed ahead, pulled on the throttle (was used to riding a bicycle and braking), then in a last ditched attempt not to go through the fence put my feet down. Head went through the fence, back wheels of quad bike went over my calves. And there I was virtually prostate and stuck. It was very funny, took 3 men to free me and I had tyre mark bruises on the backs of my legs for quite a while. Haven't been on a quad bike since!!!
Second one was (as an adult) I took a meat pie out of the oven, for some unknown reason removed it from the foil tray and carried it (in oven gloves) across to the waiting plate. The pastry on the bottom crumbled and the very hot steak fell out onto the top of my foot. 2nd degree burn. A&E nurses thought it was hilarious - said it was the funniest accident they'd seen that day!!! It was bloody painful, especially because it became infected. I ended up bandaged toe to knee for 2 weeks and still have a scar on my foot 25 odd years later.
3rd one was a few years after the meat pie incident, I put my hand into the back of a kitchen draw to get something, pulled my hand back and it got stuck - I had impaled my finger on a serrated knife. I immediately pulled the knife out of my finger and sprayed blood everywhere - it looked like there had been a murder in my kitchen. Luckily the knife had gone in through the pad on the tip of my finger, missed the bone and come out right on the edge of my fingernail. I still have the scar there as well. That fingertip was numb for a long time.
I am sure if I try I can remember more - but the above 3 are outing enough if anyone on here knows me, so I will stop now!!
