I once contacted a 220 line with a chisel. I found myself on the other side of the room before I knew what happened...not an experience I would care to repeat.
I was changing an overhead light bulb in a country that has 220. A child turned the light on as my hand was on the business part of the light fixture. I was standing on a chair, blacked out and thankfully fell off the chair. Someone tried to pull me off and they were thrown to the ground.
