Circa 1980 someone at MIT showed me a little pamphlet floating around, created by Gian-Carlo Rota, of all the integers between I think 1 and 1000, listed purely in English, alphabetically. The idea that this could have any conceivable use struck me as so absurd that I could not stop laughing for quite a while.
