I remember when Joker's Wild was first syndicated in 1977, Jack Barry said on an early episode something like "...we're no longer bound by a network's limits...if you can win $100,000, go ahead and win it..."
In the early '80s the CBS O&Os bought the show, and all of a sudden the show was bound by CBS's winning limit, which at that time was $50,000. I remember seeing this episode when it first aired and being surprised, because I thought the "$100,000" statement still prevailed. Joe Dunn's last episode aired around March 1983.
Good thing Tic Tac Dough wasn't on the CBS O&Os when Thom McKee was on!
