My spies inform me that, yes, Game Show Network is about to air the final network I've Got A Secret from 1967 (Friday night/Saturday morning) and that they will then go back to 1955 and rerun all the episodes they've run before. That will involve again skipping over some episodes that do exist in their library but which would require heavy and costly editing before GSN would want to rebroadcast them. Mostly, this involves the removal of cigarette commercials that (I assume) are integrated into the show itself. God knows we can't have America watching Winston ads at 4:00 in the morning.
I have no listings for what airs the two nights following the rerun of the last CBS show, but Monday night/Tuesday morn, they're scheduled to air the 12/2/53 show with special guest George Raft. The next night, they run the 12/23/53 show with guest Paul Hartman, then that's followed by 10/13/54 with Boris Karloff and 2/2/55 with Ed Sullivan. The debut episode was June 19, 1952 so they're only running about a half-dozen shows from the program's first three years.
Among those omitted is the episode where the celebrity guest was actor Monty Wooley, whose secret was "I sleep with my beard under the covers." The panel failed to guess it and, when it was revealed, panelist Henry Morgan asked, "Now, Mr. Wooley, tell us. Do you really sleep with your beard under the covers?"
Wooley replied — on live TV and referring to the producer of the show — "No, but some damn fool named Allan Sherman told me to say that."
