This thread reminds me of an essay by Isaac Asimov I read in high school. It was call "A Piece of Pi", and near the end, he had the following footnote (bolding mine):
Quote:
By 1955 a faster computer calculated pi to 10,017 places in thirtythree hours and, actually, there are interesting mathematical points to be derived from studying the various digits of pi.

I've been annoyed by that last little comment ever since. How can he be so cruel as to taunt the reader with a comment like that, but then not say what any of these interesting points are?
