The humble Priest/Padre from the Series Mash!!
I always loved Richard Dawson (he had a small role in Mash, I believe).
He was amazing on Match Game (in the 70s) and the original, the best Family Feud (with respect to Ray Combs RIP).
I was a nerdy kid who would watch Game Show Network and google (then it was excite.com for a search engine) the hosts/panel. Found out so much about those obscure hosts. To Tell the Truth, What's My Line (RIP Larry Blyden, died in an auto accident in Italy) etc.
RIP Bill Christopher, I didn't know ye, but obviously you were special.
On Sunday nights on GSN, they would show old black and white 50s game shows with the current (at the time) celebs. It was dazzling. It was a thing back then to be a panelist if you were famous, from Lucille Ball to Liberace. All sorts of celebs would grace the stage of those old game shows.
