Again, I'm not following, although I agree there was probably a screening for first-timers. However, some of the best Clark Pyramid players were B-list at best: Mary Cadorette, Stuart Pankin, Henry Polic II, etc. Most of the guests were supporting cast members on the popular shows of the day, but were hardly people you'd see on Johnny Carson's couch.
I really agree -- if you can play the game well and develop a friendly rapport with contestants, staff, and emcee, you'll be called back time and again even if you're a virtual unknown with 99% of the viewers. If you're
really good, you'll be invited back for a Tournament Week.
I'll try to explain what I mean again -- contestants go through a screening process to pick those who the show wants. Much like that, I would think celebrity-based games would do something similar for celebrities -- regardless of name recognition, if you can play the game well you're going on-camera.
Donnymid, on the other hand, seemed to want those who could play the game "moderately" over those who had proven themselves great on
Pyramid over the years (such as Betty White). The moderate celebs were usually C/D-listers.
Oddly, the series veterans seemed to be put up against "Countries Surrounding Pakistan", "Shows Developed By Fred Silverman", "Programs Gary Coleman Has Appeared On Through A Cameo", "What Air Would Say", "Things Found In Al Capone's Vault", "Smells Found In The Back Of A Bus", and "Things To Which You Might Lose A Key" much more frequently than the others.
