When I lived in Sweden I went to the gas stations wash rack to clean the car in the winter...
I seemed to be the only one there except I could hear a radio in the other end , probably 10 bays away...
suddenly I hear a faint "help, help, help"...I go looking.
in the last stall I fine a Peageot with a man standing ,leaning over the pass. fender, hood up, radio blaring.
I walk around...he has his left thumb stuck in under the wiper mechanism ,really stuck there...

find out he had been working on the wipers as they wouldnt move, and had radio on, so he had ignition on...working from the pass side and drivers door open.
As he got the wipers to work ,the arm slip over his thumb, clamped it and got stuck...he couldnt reach the ignition to turn it off...and couldnt reach any tools!

I had to turn off ignition ,then release the nut on the wiper motors arm...he was fine.

But what a stupid thing to do...and he was there by himself..Had I not decided to wash my car he could have been there for hours , maybe all day!....LOL
