Well, if you're captured by an alien who asserts that s/he has
calculated pi to a gazillion decimal places, and your survival depends
on determining whether the claim is true or not, you can check a few
digits at random and either be certain it's false or 99.99. . .% sure
it's true.  Never know when *that's* going to come in handy; in fact
IIRC this very plot was once used on McGyver.
