Aaaah, fun with electricity.
I was an electrician in the Navy long ago. Very often we'd be short of test equipment and resorted to testing 120v circuits by leaping in the air(you didn't want to be grounded to the hull of the ship when you did this), and smacking two fingers across the terminals to be tested. If it was live, you felt it, with no harm done. Rumor has it that someone tried this on a 440v circuit and lost two fingers, but I have no personal knowledge of that.
I did get a good 440v jolt once though. I touched a live terminal with a screwdriver while standing on an aluminum ladder, and felt the currant pass up my left arm, through my chest and out my right arm where it gripped the ladder. It threw me off the ladder and about 8 feet through the air. I suppose I could have gone farther but I hit a wall and slid to the ground where I sat, conscious but unwilling to move until my heartbeat settled down to something resembling normal.
We'd also have fun by charging capacitors, carefully holding them so that we weren't touching the terminals, then tossing them an unsuspecting crewman. Its amazng how people will instinctively catch anything you throw to them. Once they caught it, they'd usually touch both terminals of the capacitor and get a harmless, but unpleasant zap.
