"One does NOT need to touch both hot and neutral to get a shock. All that is required is an electrical path from hot to ground. That can happen innumerable ways: damp floor, kid spilling his drink, or any other innocent means of being in contact with a grounded object while cleaning."

You would have to be cleaning the outlets with a conductive material to get shocked. Hint: do not use a coat hanger or similar item to clean your contacts. Tell your kid not to stick his fingers in both holes at the same time.

Geoff, you would have to be cleaning ONE outlet, the hot one, with a material that becomes conductive, for one reason or another; e.g. wet with perspiration. That and a path to ground, no matter how elusive or invisible.

And Geoff, I did not insult you nor your intelligence, so pray do not insult mine. There is no need for that.

Now you're being ridiculous. And argumentative.

Yeah. Right.
