Later in the show, a common thing was for the celebrity to challenge the panel in some other game. This later became the main use of the celebrity part of the show, and they no longer pretended to have a secret. Instead, the celebrity would just come out with a challenge for the panel. Several of these challenges later were the main idea used for other game shows. For example, a game in which Woody Allen challenged the panel to guess words by what children had said they meant, which became the basis for "Child's Play". Or two challenges with Peter Falk and Soupy Sales in which the panel had to guess who a celebrity was after being show a photographs of them as a baby and others as the aged, which later was used for the show, "Face the Music".
