Okay, here's one: during Richard Dawson's stint on Match Game, host Gene Rayburn read off a Hogan's Heroes question. Possibly it was Dawson's usual cool veneer, or possibly he was a bit irritated, but he didn't crack a smile and didn't appear to take it as a compliment. I can't remember it word for word but it was something to do with a suggestion to Colonel Hogan of what should be added to the tunnel, and the popular answer was "toll booth" because of all the traffic down there.
