Yeah.  You and I both.  You'd have loved our electric chair I built when
I was a yound teenager.  The chair was simple.  A sraightback wooden
chair had an aluminum plate fastened to the seat and another fastened
to the back.  The plates were connected to a 15,000 volt neon
transformer.

After I got it built, the obvious question arose.  What to do with it?
A bit of teenage hormonal thinking resulted in it being turned into
a test of manhood.  The test was simple.  A variac was hooked in series
with the primary.  The contest was to see who could sit in the 
chair and see who could turn the knob up the highest.  As the inventor,
I was exempt from this, of course.  We were smart enough to have
a dead-man's switch (apropos, huh?) in the circuit.  If I only had
a video camera.  You'd be amazed at the things the human body
can withstand in the process of one acquiring one's manhood (or losing
it as the case may be :-)

Yep, amazing we made it to adulthood.  Makes me chuckle when I 
think about the risk-sterile society some would now force on us.
