This is a bunch of vignettes of how the writers of this animated cartoon would like to see some scenes in classic fables such as Sleeping Beauty, Tom Thumb, The Grasshopper and The Ant, The Boy Who Cried Wolf, Jack And The Beanstalk, The Wolf In Sheep's Clothing, on and on.
It's an interesting idea for a cartoon but the trouble is that the humor in 1942 was vastly different from today. Almost all of these jokes would be looked at today as really stupid. Prince Charming almost chokes Sleeping Beauty screaming at her to "get up!" while Tom Thumb is really a big, fat kid, etc. It goes downhill, believe it or not, from there.
The only thing I laughed at was the dog in the Old Mother Hubbard where he exposes the old lady as a "food hoarder." The rest of it is really too corny for laughs, although I did smile at the ending. A couple of them were not meant to be funny, but to be plugs for the war effort as this was made in the middle of WWII
This short was included in the DVD of the Errol Flynn movie, "Gentleman Jim."
