This happened me, i was fixing a dialup connection in my attic and had no strippers, so i used my teeth. i was lying flat on my stomach underneath a desk, and i bit the green wire. As i did this the red wire moved and touched me on the cheek i think. Next thing i know, there was a blue flash, and i was standing up perfectly straight after lying on the flat on the floor! ;D Seriously, how my body managed to jump back like that without hitting my head off the desk, i do not know. ??? One of the cool things is that the every person has a different resistance in their bodies. There are some, if not few people that could handle a mains wire, (240V) and not get shock.
