Mystery guests would usually attempt to conceal their identities with disguised voices, much to the amusement of the studio audience. According to Cerf, the panel could often determine the identities of the mystery guests early, as they knew which celebrities were in town, or which major movies or plays were about to open. On those occasions, to provide the audience an opportunity to see the guest play the game, the panelists and host would typically allow questioning to pass around at least once before coming up with the correct guess. As Cerf admitted in the episode broadcast on November 27, 1966, his wife, Phyllis, was frequently told the name of the mystery guest beforehand.
