These early '30s Tom and Jerry (human) cartoons like to start with a famous song from the old days. Most of them are very familiar to anyone over 50 years of age. In this cartoon, it's "I'm Looking Over A Four-Leaf Clover."
These short animated films, which also go under the title "Dick and Larry," are also very inventive and a ton of fun to watch. I wish there were more of them available.
Anway, in here we then see a dancing cow in her short, polka-dot skirt. From there come some very clever sight gags, such as a dancing easel as the big guy paints, a pen which works for the little guy but not his partner, and a big assortment of crazy things where one thing magically changes into another. It's tedious to write about, but really fun to watch because events are so unexpected. These Tom and Jerry cartoons are mainly just absurd humor put to use in animation and, frankly, I find it fascinating.
The imaginations these writers had was fantastic. For example, a piece of string turns into a saxophone, the notes from the music turn into ducks, the saxophone turns into a dancing animal, on and on....just wacky stuff.
This cartoon can be seen on the DVD called "150 Cartoon Classics."
