As long as we're telling stories about electric fences, I once had
a farmer show me how he tested his electric fence.  He took a long
piece of green grass, held one end between thumb and forefinger, and
touched the other end to the fence wire.  Without about eight
inches of plant material between your hand and the fence, all you
feel is a little thump when the pulse comes through.

He even did an impromptu demonstration of Ohm's Law, by showing us
how the thump got stronger if you put less grass in the conduction
path. :-)
