Dangerous Dan McFoo is a 1939 Merrie Melodies/Vitaphone animated short directed by Tex Avery, produced by Leon Schlesinger, written by Rich Hogan and based on a poem by Robert W. Service entitled The Shooting of Dan McGrew. It is especially noteworthy insofar as the main character's voice as performed by Arthur Q. Bryan would later be used as that of Elmer Fudd. Other voice performers include Mel Blanc as the villainous stranger and Robert C. Bruce as the narrator. All voices are uncredited in the film. This is the first Blue Ribbon to use custom letters for their titling, until somewhere in the 53-54 era when both Lydian and Newland typefaces were used for the blue ribboning.
Dan, an anthropomorphic dog, is in the rear of the arctic "Malibu Saloon" playing pinball. A villain enters and sees Dan's love interest who is referred to by the narrator as "the girl who's known as Sue." Sue, from the villain's perspective, morphs into the image of Bette Davis but tells the villain in the voice (and catchphrase) of Katharine Hepburn: "I hope Dan mows you down, really I do." A boxing match ensues during which Dan accuses the villain of cheating; four horseshoes - and a horse - are found in his boxing glove. The fight continues with no outcome and the combatants are given dueling pistols by the narrator. The lights go out, shots are fired and a woman screams. When the lights come on, Dan is seen lying on the floor. His girlfriend says repeatedly, say something, say something and Dan McFoo wakes up and says "Hello!" as the cartoon ends.
