Celebrities help contestants guess the names of people or places by offering incomplete sentences as clues in a popular series known for the tag line `It's not what you say, it's what you don't say.' Airing in prime time in 1964, the show ran on two networks and later in syndication, and its guests included Richard Chamberlain, Vincent Price, Mel Torme, Rod Serling, Dina Merrill and Frankie Avalon.
