I think that I have seen a few of those knuckleheads before at a couple of places that I was working at the time. The Jerry rigged ladder rings a bell, the idiot would up with a broken leg and pelvis and a some internal injuries. What a maroo, although I was not happy about anyone getting injured, I experienced some rather perverse enjoyment out of it because he was warned by me and several others not to attempt what he was doing. After nine months of being off, when he finally did return, I told him to stay the hell away from me as he was dangerous. (Three months after that the place fired him after yet another 'accident'.
Be safe and live to tell about it.
