I tried shocking myself with my dad's about 10 or so years ago. Didn't hurt as much as I thought, although it was just a short shock into my gut. It didn't even feel as bad as touching a couple of wires sticking out of the wall. I recon that's because there's alot of voltage, but not alot of current behind it. Maybe I'll dig it up for you guys and experiment on my friends to find out their reactions.
