I have been whacked by 120, 220/240, 440 capacitor I left in my pocket burned a hole in my jeans and got me, oil fired furnace transformer which was the worst of all of them, caused me to black out.
Funniest story of them all.
I had a friend that somehow got a hold of a cattle prod. He carried it in his car as a defensive weapon. He decided to see just what it would do if he got someone with it and used him self as the test subject.
In his words: "I took the prod out of my trunk and turned it on.... I remember touching my leg with it and then waking up with a huge lump on my head, I had shit and pissed myself and had no idea how I got on the ground"
He has passed out at the back of his car and smacked his head on the bumper on the way down, shit and pissed his pants and was out for god knows how long!
