A friend of mine, who is a graduate student in linguistics, told me the following story. (Caveat: this is urban legend-ish; the details could have been exaggerated.) Once Chomsky was giving a lecture on different features of languages. For some feature (call it X; I forget the technical details), he boldly asserted that no human language could conceivably do X and proceeded to go on and on about why X was absolutely impossible. There was a hand from the audience. "Estonian does X."
