by the fact that, like What's My Line?, the top payoff never increased with inflation, and the money eventually became somewhat secondary to the gameplay, with the cash awards not even mentioned at all by the end of the series. Similarly, the panelist chosen to question first eventually became a strategy by the producers. When a secret fell within an area that a panelist was knowledgeable on (most commonly Cullen with mechanical, scientific or sports secrets), they would often be chosen first, to give them no preceding clues during their questioning. On occasion when a secret referenced a panelist, the order was usually chosen to put them last. Following the revelation of a guest's secret, either by guessing or by the host's revelation once the game was over, the host typically either interviewed the contestant about their secret, or, if applicable, the contestant did some kind of demonstration of their secret. These demonstrations sometimes included the host, and occasionally one or more of the panelists. Beyond the standard celebrity guests, several notable people with secrets appeared, including Colonel Harland Sanders ("I started my restaurant with my first Social Security check"), drummer Pete Best ("I used to be one of The Beatles"), and a 95-year-old man, Samuel J.

Sgt. Ira Jones, who served as Elvis Presley's First Sergeant in Germany, made an appearance. Scientist Philo T.

Guest rounds On each typical episode, a celebrity guest came on the show with a secret. The celebrity usually opened the episode by coming out from the behind the curtain and saying "my name is [Name] and I've Got a Secret!", though sometimes they would say "and this is I've Got a Secret!". Early in the show's run, the celebrities would indeed have actual personal secrets similar to the other contestants. However, producer Allan Sherman later admitted that these celebrity "secrets" (such as Boris Karloff being afraid of mice) were frequently
