Nerdy even for THIS group, but I've become obsessed.
I've found a reference to a silly incident in a 1953 episode that I strongly feel like I've seen before, even though it's from an episode that's never been re-aired in its entirety. According to the newspaper article, Bill Cullen is playfully upset because guest Peter Lawford kissed his wife in public. So he turns to a fellow panelist (presumably Jayne Meadows), kisses her, turns to the camera and says, "Two can play at that game, you know!"
I want to say that maybe it was part of an early GSN promo built around Bill. Does anyone else have this memory, or (even better) could point me to the existence of it on a recording?
