Oaklevel: I copied this from the internet for you. A ground wire is needed for the outlet or the box needs to be grounded. Either way, a ground is needed:
Old-fashioned two-prong receptacles connected to two-wire cables don't have the
ground wires that protect people and electrical devices in case of a fault. Yet it is possible to retrofit a new three-prong or
GFCI receptacle into the same outlet box
without any rewiring, as long as the box itself is
grounded.
