Some small televisions, for example, have one side of the AC line tied to the "frame". It's supposed to be the neutral but if somebody screws up the wiring in the electrical panel or the outlet box you can end up in lots of trouble. This isn't "mis-wired" it was standard practice up until around the late 60s, early 70s. Not only was one side of the circuit normally wired to the frame, but the concept of a polarized receptacle did not yet exist either. (Let alone a 3-prong duplex outlet as a "standard.") The Electrical codes and construction standards have changed radically since the days of "tube" and discrete component based devices. T.T.F.N. William H.
