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

Doing barefoot trackstands, somehow caught my big toenail on a mudguard rod. My toenails are big thick & strong, but the rod went right under and tore the whole nail off as well as gouging into the flesh below. That was nearly a year ago and it hasnt grown back properly yet.

xD
this is almost the same as what happened to me, but I was mounting a rescue attempt to help my sister locked in a bedroom by a backdraft of air (wedging it shut tight).
I decided to kick it down but as I slammed my foot into the door, my big toenail caught the door handle and I watched in horror as it flew off.
I grabbed the nail, ran into the bathroom and slammed it back into place over a bloody, slippy, oozing mess!
..the pain....AGAIN, THE PAIN =[

~ Contracted cerebral maleria by accidently skipping my daily dosage of Advacor and Paludrin over a weekend. Luckily no drain bamage even tho I was in and out of a coma for 2weeks. On the plus side I lost **shitloads **of weight and could fit into size 32 jeans (from 38) once back home! that’s when women first started to notice me, so it turned out swell.

and lastly
~ as a child of 11 I dissasembled a plug so I could get at all three pins, insert them into a live socket. Never felt a vibration quite like it. I didnt die, just came away with a weird smell and taste in my mouth.
