fun story: got 240v (no idea what ampage that would have been) from the back of a wanky old TV when I was ~12 years old, threw me ~8 feet across the bedroom. Frightened the fucking life out of me
eta: weirdest part was feeling the 'wave' my arm was doing, reminded me of the perfect body pop wave (this was back in about 1984). Very strange feeling as it went through my arm.
