IT being unlawful to set man-traps and spring-guns, a gentleman

IT being unlawful to set man-traps and spring-guns, a gentleman once hit upon a happy device. He was a scholar, and being often asked the meaning of mysterious words compounded from the Greek, that appear in every day's newspaper, and finding they always excited wonder by their length and sound, he had painted on a board, and put up on his premises, in very large letters, the following: "_Tondapamubomenos set up in these grounds_." It was perfectly a "patent safety."
