Bosko runs a hot dog stand at an amusement park. He sells a hot dog to a bow-wow-type dog; but before the dog can eat it, the hot dog cries out, "Mammy!" in imitation of Al Jolson. The dog happily replies, "Sonny boy!" The dog and hot dog kiss and go off skipping and barking, joyfully reunited. Meanwhile, Bosko sneaks away from his hot dog stand so that he can compete as a jockey at a nearby racetrack. Bosko's horse is only mechanical; but his pluck and quick-thinking will give him an edge over his competition. Written by J. Spurlin
Watched this Bosko short on YouTube and I agree with the previous poster that this was amusing and nothing more. Best sequence was indeed the hot dogs dancing without a care despite their intended purpose! The "Mammy and Sonny Boy" gag may be pretty obscure for anyone who doesn't know Al Jolson, otherwise it may be considered racist by others though in this case I don't think any real harm was meant by it. If the mouse drawn here looks a little familiar, it's because the directors, Hugh Harmon and Rudolf Ising, once drew for Walt Disney when he did Oswald the Lucky Rabbit who somewhat resembles the future mouse that would put Disney on the map of animation history. Worth a look once for anyone interested in this sort of thing.
