I've been on sort of a You Don't Say! kick -- the game is a *lot* of fun and requires a different kind of creativity (in terms of clue-giving and -receiving) than Password does. It's too bad that neither of the revivals lasted long; I think it could be successful again in the right hands.
At some point they must have tightened the rules for clues spelled the same as the portion of the name the player was going for. In the '64 Day/Landon episode, one contestant goes directly for "crane" as part of "Ichabod Crane." (On the '69 Cole/Grady episode, a contestant does get buzzed for trying to elicit "God," but I think that was because it was a proper noun in the context the contestant was going for.) But on one of the available '75 episodes, a contestant gets buzzed for trying to elicit "ark" as part of "Arkansas". Is there some fine distinction between these that I haven't picked up on?
