Early 80s, in high school, Wink Martindale's \"Tic Tac Dough\", back (I believe) at the Golden West/KTLA studios; over the next few years, I would catch many TTD and TJW tapings at both KTLA and the ChrisCraft/KCOP lots, as well as a few one-off appearances during my first collegiate go-round (the details of which, I'm afraid, are forever drowned in a collegiate-associated alcoholic haze).
Oddly, while I've tried out for shows like Scrabble, J!, Card Sharks and SotC, I've never (to my recollection, anyway) actually gone to watch a show for which I've auditioned (or vice versa). Never have been sure whether or not there was some Deeper Meaning to that fact....
