Thanks for posting the obscure shows(Diamond Head, The Fun Factory) you posted so far Jamie! Now with Pass The Buck, the "Sue has the flu" episode from May 8, 1978, was that the last episode to air on GSN? Also, I'm assuming that the Soap Opera College Challenge WOF episode was from November 24, 1992, if there's no reference to Thanksgiving. For The Fun Factory, only 80 episodes were aired on NBC but only 2 of them were aired on GSN and I'm not too sure if the UCLA TV & Radio Archives Center has the same 2 Fun Factory episodes that appeared on GSN, but the one you posted happened to be from one of the early episodes, if not, the series premiere week and for The Gong Show 1978 episode, that was from the 8th-to-last week of the NBC run, but I'll leave that to the folks who have old TV Guides for Gong Show and also the 1976 Tattletales episode with Gene & Helen Rayburn and Leslie Nielsen but pyrfan is an expert so far on those.
