Get out your trusty old voltmeter, set it to the 200VAC range, and stick one probe into some moist earth in your yard, and the other probe into the hot spade socket of an electrical outlet (that's the right-hand side one of a 3-prong outlet when the round prong hole is on the bottom).

Cool, eh? Tell us what voltage you measured.

Then repeat the experiment, connecting the voltmeter to the neutral socket instead of the hot socket on the outlet. It will measure 0.0V --> that's the one you can safely lick, if (like Bitt) you're into that sort of thing.
