One night, after a particularly bad thunderstorm, our phone lines started picking up an AM radio station before you placed a call. My parents swore up and down somebody had left a phone out of the receiver and after unplugging every station in the house, we realized the problem. Now I can still pick up that same radio station if I hold the male end of a cable plugged into a guitar amp. At least the station plays decent music!
