I recall how one fellow carefully explained that electricity needs a
complete circuit to travel, and that since he was wearing rubber soled shoes
he wasn't grounded. To test his theory, the story goes that he peed on the
fence. Apparently, either there was an AC component to that fence voltage
and his understand of capacitance was lacking, or those boots weren't non
conducting (black rubber conducts). At any rate, he apparently felt it.
His eyes uncrossed sometime later.
