Catroaster
Catroaster was a philosopher of Ankh-Morpork whose curriculum vitae might have been longer if the Guild of Merchants hadn't taken great offense at his aphorism: "When a man is tired of Ankh-Morpork, he is tired of ankle-deep slurry." Shortly after this announcement he was found face down in or on the river, following the Guild's short re-education program.
Annotation
Although not well-known elsewhere, Catroaster seems quite popular in Poland, where he is associated for some reason with strikingly-built female cyclists in very tight Spandex outfits.
