Indiana had a sumptuary law prohibiting the smoking of cigarettes, and a showman was exhibiting a trick chimpanzee in a country town in the vicinity of South Bend. One of the tricks of this animal was to smoke a cigarette, for which he was arrested and brought before a justice of the peace. His keeper pleaded that the animal did not know that he was violating the law, but the justice solemnly replied that ignorance of the law excuses no one, and the chimpanzee was fined five dollars which his keeper paid.
