And on a related note, my winner for the prize of all-time poorly designed
products:  the Carver C-9 Sonic Hologram Generator.  Why?  It had a
non-polarized AC plug and a polarized convenience outlet on the back.  And yes,
flipping the AC plug in the wall would indeed cause the large slot of the
polarized outlet to become hot!  When I discovered this I quickly painted one
side of the AC plug's sheath white to avoid surprises later...
