Bit like the UK student wheeze of getting (or not) their professor of
electronics testing the earthing of the phone system by phoning him and
getting him to fill a bucket with water and then putting a foot in it.

It was funny no matter how true it was...

I read another one in an electrical contractor magazine.

An individual reported getting shocked when he went in his aluminum back
door. People thought he was nuts. Turned out, when a contractor was
putting in some siding that had insulation with a aluminum backing on
it, a nail penetrated both the siding a a live wire that was too close
to it. This made a path somehow to energize the door.

The last knew in 1977, Nevada had one line of ground return. As far as I
can remember
it was about 10 miles long.

Phantom circuits using two pair of wires did not use ground return. And
the quality
of speech was as good as the "side" circuits with maybe reduced loss.
The "side" circuits
have to be identical though. If they are not, then from the unbalance,
you can get noise and power line hum.
