This slim volume is a collection of mathematical jokes, quotations, and
humorous items. Some of the jokes are good (but none as good as the
unaccountably absent Impure Mathematics
-- aka The Adventures of Polly Nomial), but many are rather strained. And
the best ones are reprinted from Weber's much superior
*A
Random Walk in Science*.

One of the better entries is a mathematical paper on "Busprongs" -- which I probably appreciated because I have recently had to read a (real) paper that had a lot in common with it. The entry comprises not much more than a bunch of arbitrary definitions and unmotivated proofs, and is a great spoof of the sort of paper that gets mathematics a bad name.
