As far as I know, only a game show in the broad definition that includes
Whose Line?, this was a 1951 summer replacement series that only ran for five weeks. Three of those five are part of this collection, along with an unsold 1959 pilot for a revival attempt. The original features a young Jack Lemmon. The revival pilot has several familiar faces, including Kaye Ballard, Alice Ghostley and Larry Storch (who is introduced but ends up not playing). Eighteen bucks.
