Art's right, I've been hit by this myself a few times in my younger days fixing
TV's.

There was a guy in my high school electronics class that used to discharge
pictures tubes by hand (or two hands, one on ground, and one holding a screw
driver's blade that he stuck under the cap). Yeah, he was a football player.

He also stalled a car once by somehow shorting the ignition coil to ground
through himself. I'm not sure how he got into the ignition coil, I was too far
away, but I saw the car stutter when it stopped getting its spark, and
eventually die. It was one of the stupidest things I'd ever seen, and one of
the funniest as well.

He played it off like it was just a joke, but you could tell it *really* hurt.
Even though he said it was no big deal, no one could ever get him to do it
again.

Jocks!... ;-)

FWIW: We were taught (and I haven't done a google search to verify this) that
10ma (through the heart) could cause problems with pacemakers and those with
hearts that have irregular rhythms.

100ma through the heart can (and almost always will) stop it, and will probably
kill you.

Maybe someone could look it up and see if my electronics teacher was telling the
truth (this was 1974, there might have been more research done since then.)
