Every machine has a maximum string size. What you really mean is "a maximum
string size small enough I've bumped into it often enough to be annoying."
I knew a professor who taught "There's two kinds of programming languages.
Those that support bounds-checks on their fundamental data types, and those
that don't know they need to support bounds-checks on their fundamental data
types." (Or something to that effect.)

A match will do just as well.

Regarding cigarettes, yes.

Indeed - I remember the classes on that (not that I took them, but I
worked in the computer lab so helped students who were having problems),
it was really interesting.
One of the things that made it interesting was that each table had two
printers on it that shared a print queue. The way HG would print, you
could end up with half the graphic on one printer, and half on the
other. :-)

Interesting, I hadn't noticed that - but I hadn't really thought to
look. :-)

Yeah, but it still would want to go to ground, and the water doesn't
provide a grounding influence that's stronger than staying with the wire.
