Electrocution...
like a working on a coil pack on a V-8 (distributer power wire was damaged and I had to fix it), and forgetting that the battery is still connected, and you are leaning on the car making a ground of your self, and your bro is in the car and happens to turn the key...

I'm a union electrician, I've been hung up in 120, 277 and gotten hit by 480. 277 is truly excruciating if there is a load on the neutral.
