Some absolute genius fails here.
After slicing through the cable on a hedge trimmer I purchased one of those two pronged garden cable connector things and wired them on. Sadly I wired them on the wrong way round so that the male end was connected to the mains. Not being aware of this fail and to reduce my chances of cutting the cable a second time I passed the live cable through a hole in my pocket intending to pass it back out the top of my shorts. It rested momentarily on my bell-end.
Another time whilst using a sledgehammer I glanced a post whilst on a full swing, the sledge continued to swing down and round straight into my lower shins throwing both feet backward and my upper body forward so that I smashed my face into the same post
Finally my number 1 fail. Climbing on some industrial racking I lost my balance and had no choice but to step off and try to make best the landing about 15ft below. No great issue only the was a set of pump trucks beneath me and I landed upon the upright lever handel with leg either side. I had testicles the size and colour of a pair of auborgines for weeks
