I had a vague memory - a strange recollection in the back of my brain - of a game show I saw once or twice in the 1970s. A game show that was just horrid.
I forgot it for many years until I ran into a game show site that mentioned it. Now, I've found a link to a streamed version of one of the only two surviving episodes from the series.
The Magnificent Marble Machine
The show ran on NBC for a few months and the producers hoped to capitalize on the pinball craze of the time. With the cheezy graphics and music and the massive pinball machine that seems to dwarf everyone on the show, it's a long strange trip back to the worst of the 70s.
