HANS CONREID for FRACTURED FAIRYTALES
Actually I believe that was Edward Everett Horton.
retrorussell is correct, "Fractured Fairytales" was narrated by Edward Everett Horton. while "Dudley Do-Right" and "Rocky and Bullwinkle" were narrated by William Conrad. And I don't remember, whether he also narrated it, or just did the voice of Aesop, but that was Charlie Ruggles.
It is understandable the confusion with Hans Conried though, since he was the voice of Snidely Whiplash on "Dudley Do-Right."
Hans Conried was both a great voice actor and character actor, appearing many times, both in films and on TV. But, he apparently never did much narration, except for some Seuss stuff such as "Dr. Seuss on the Loose" and "Horton Hears a Who." His last professional job was also as narrator for the video "Fables and Legends."
All those mentioned are greatly missed.
