As soon as I disconnected that battery pair, I popped a couple of the
caps to see what I could see. The acid in them went from clear to mucky
gray. If the bulging and the distorted plastic weren't enough of a
clue...

Good point. There's actually some psych research that claims results
significantly above random for a first guess if you really don't have
any clue about an answer on a test (even in a field you know nothing
about.) The second guess, interestingly enough, is *much* worse,
percentage-wise.

Ditto!

That's exactly what I find so annoying about it. As far as I know, the
Evil Battery Pixies hypothesis is still in the "pure conjecture" stage -
and the one and only EBP detector got broken while filming Ghostbusters,
so there goes even _that_ theory...
