A regular set of three celebrities, paired each week with three guest celebrities, tried to identify famous personalities from their partners' responses to odd questions.  ("If you were a piece of furniture, what piece of furniture would you be?")  In a different game played occasionally by one of the three teams, partners took turns describing famous personalities any way they could for additional points, a precursor to the Pyramid main game.

Bill, Peggy Cass and Larry Blyden made up the original regular team, and Bill Leyden was the host.  Cullen left the show after a few weeks and his chair became a fourth guest seat. Starting on September 29, approximately halfway through the show's six-month run, Blyden took over as host.  Bill returned the following week and stayed with the show for the final three months while Blyden's chair became another rotating position.

All-celebrity games never seem to click with the viewing public (witness Personality and Password All-Stars) and this oddity was no exception.  It did, however, manage to draw a few exceptional names in its half year on the air, including Burt Reynolds, William Shatner and Eli Wallach (see below).

VIDEO 
No regular episodes are known to exist.  The pilot, hosted by Broadway and soap veteran Ron Husmann, is available for viewing at The Paley Center in New York and Beverly Hills.  (The picture above is also from that pilot.)  In the pilot, Bill, Betsy Palmer and Larry Blyden were the "regular" panelists and in one round, they even played with civilian contestants.

EPISODE GUIDE 
The series is almost certainly lost forever, but here, courtesy of researcher extraordinaire Brendan McLaughlin, are the celebrity line-ups for virtually every week of the series' six-month run.  Why?  Because he's as obsessive as we are, and his hard work shouldn't go to waste.
