My parents were not the biggest of game show fans, but would watch with me when I was a child as long as the show was appropriate. I do remember them being fans of Ed McMahon's "Whodunnit," but that was more to them being fans of the mystery TV genre, guessing the culprit at the end, etc. They saw it less as a game show but more of an extension of, say, "Cannon" or "Vega$". They also were casual fans of Davidson Squares, saying they preferred Davidson's hosting to Peter Marshall. (*)
My father and I bonded in front of the TV for a week to watch, of all things, "Hot Potato." Michael Winslow was one of the celebrity players that week, and my parents had just seen the original "Police Academy" on video (I was only 10 or so, so the R-rated "Police Academy" was a no-no). My dad enjoyed Winslow's antics in the film, so he watched specifically to catch Winslow do one of his sound effects (IIRC, Bill Cullen would have Winslow do one of his vocal tricks after an ad break each episode). My father even mentioned to me that he hoped Winslow made "more family-friendly films" as I would enjoy his work.
Years later, while in college, I interviewed Winslow to promote a stand-up set he was doing near campus. Near the end of the chat, I mentioned watching "Hot Potato" with my dad and how we both got a kick out of his act. He was surprised I could remember the show (he said everyone asks him about "Police Academy" and "Spaceballs), but thanked me for the memory. He also mentioned that Bill Cullen told him that his vocal antics would have been a hit on Ed Sullivan, and he considered that a great badge of honor.

(*) -- This may be a family thing. My grandparents on my mother's side vented a few times about how Dennis James was a far better host than Bob Barker on TPIR because James was a "Jersey guy" and Barker was a "farmhand." My mother explained after their passing that they were still upset that their oldest son (my uncle) moved from NYC suburbia to Nebraska for college and adulting and pretty much dismissed all Nebraskans as nothing but farmhands. They also watched anyone but Johnny Carson after the late local news for the same reason.
Yes, I know Barker was born in Washington state and raised in South Dakota. But the fact my grandparents rejected both Barker and Carson because they are somehow connected to my uncle going all "Green Acres" is, well, different.
