Daffy Duck (Mel Blanc) is way out of his usual element----or is he?----in 1939's "Daffy Duck & the Dinosaur", directed by Chuck Jones. Well, this is set in the Stone Age, and Daffy is being targeted for breakfast by a hungry caveman (Jack Lescoulie, doing a Jack Benny mimic of a sort), aided by a dinosaur named Fido. Well, that's one strike. Against the caveman, that is.
Portions of this cartoon were later used, with Fido recolored brown, in Was (Not Was)' "Walk The Dinosaur" some 50 years later.
