There’s an old joke running around that goes as follows, “Lost: Bald, one-eyed ginger Tom, crippled in both back legs, recently castrated, answers to the name of ‘Lucky.'” Nigel Rees of The Quote Unquote Newsletter has been tracking down this oft-quoted joke, and so far he’s found it as far back as 1969. On another front, Fred Shapiro of the Yale Book of Quotations has made progress in tracing the origins of famous quotes, often to people other than those who made them famous. And the folks at Quote Investigator are doing their share in researching the history of those quips and aphorisms that do so much to frame our essays and speeches. This is part of a complete episode.
