Charles Nelson Reilly
Yes, you know he was simply fabulous on Match Game, prefiguring Paul Lynde on Hollywood Squares, but have you ever seen Lidsville? From the demented duo Sid and Marty Krofft, Lidsville is straight out of the what-drugs-were-they-on childrens television school of the early ’70s. Butch “Eddie Munster” Patrick falls into a magic top hat while snooping around backstage at a magic show and ends up in a special land where all the inhabitants but one are hats. Yes, hats. Who's the non-hat character? Charles Nelson Reilly, playing Hoo Doo, who’s trying to, um, do something.
