Yeah, I first heard about this in connection with catching embezzlers. People who faked books often will use a completely random distribution in the accounts, when the real world distro tends to fit Benford's Law.

"Benford's Law is the observation that most “real-world” data is not uniformly distributed - in fact, the probability that the first digit is a “1” is almost one-third, rather than the expected one-ninth. The reason for this is that the *logarithm* of most real-world data is uniformly distributed. I find this mildly fascinating." - David Dalrymple
