This assumes that you are as likely to touch one as the other.  Not so;
in things like hot-chassis TV sets, not to mention ordinary lamp sockets,
the odds of touching one side are much higher than those of touching the
other side.  So it makes sense to approximately ground one side, and try
to make that the more exposed one.
