John Charles Daly
Daly's first foray into television was as a panelist on the game show "Celebrity Time". This led to a job in 1950 as the host and moderator on a new panel show produced by Goodson–Todman, "What's My Line?" The show lasted 17 years with Daly hosting all but four episodes of the weekly series.
Gordon Ramsey
In a 1969 episode of the TV show "What's My Line?", Ramsey appeared as Bozo the Clown as a Mystery Guest. Later in the same episode, Ramsey appeared as himself without the clown makeup, requiring the panel to guess his line, which celebrity panelist Phyllis Newman did.
