Mine was Tic Tac Dough. My grandfather and I used to watch it together, I'd sit in his lap and hide behind him when players would pick a number because I didn't wanna see the dragon!
I know MG-HSH was another, though, for some reason in my memory it was just Hollywood Squares, and I had no recollection of the Match Game gameplay on the show, but I remembered the theme, the big light set, and the two hosts: Gener Rayburn and Jon Bowman.
Also, TPiR had to be one of my firsts as well, as I remember running around the house yelling \"Plinko!\" when it would come on.
