In Anita Richterman's column on May 9, 1975, several correspondents reported that they had heard the puzzle on the Bob Grant radio talk show on WMCA in New York City. This suggests either that the earlier claims of a (TV) quiz show confused a talk show with a quiz show, or that there was another unspecified quiz show that was then repeated by Grant. The majority of readers gave the answer "," an obsolete unit of measure invented by John Locke. It is unclear whether this was the answer given on the Grant show, or what the precise wording had been.
