  1. One image that's always struck me is that of the American Civil War-era wiretapper -- he would can dig up a telegraph line, strip a little bit of insulation off of two spots of the wire, clip a lead to each, and pop the other ends in his mouth. At that point he could "listen" to the Morse code traveling along the wire in the pattern of small electrical shocks through his tongue. (Having metal fillings made you ineligible for this sort of service, or at least made you wish you were.)
