"A 3-prong isn't the only way to go... if you look at most semi-modern 2-prong plugs, one side is wider than the other. This prevents them from being plugged in backwards, as a safety system. the wider prong is connected to the white/neutral/grounded side of the electrical service(fuse or breaker panel), unless of course some red-eye kill-a-watt wired the outlet wrong, which, of course, can happen with 3-prong outlets, too.
This 2-prong system insures that, for a lamp as an example, the threaded part the bulb screws into is neutral - and not switched, and only the little tab in the bottom is 'hot' and only with the switch on.
Best overall insurance?? Buy an outlet tester! They are the size of an ice cube, have a 3-prong plug on one end and 3 neon lights on the other end. $5-7 at any big-box or decent hardware store. two green...all ok. Anything else.... DANGER!"
