I remember that I first heard Johannes Brahms's "Hungarian Dances" in "The Great Dictator", when Charlie Chaplin is shaving the guy to the tune of that song. For "Pigs in a Polka", the Termite Terrace crowd continues its tradition of mixing classical music with wacky images, and they do a great job with it. OK, so "Three Little Pigs" is one of the easiest stories to spoof (they later applied music to it again with "Three Little Bops"), but how can you not like how the cartoon came out here? Probably the most eye-opening aspect is how, far from being a triad of warm, cuddly brothers, the pigs have some conflicts. The smartest one - who built his house out of bricks - doesn't like how his siblings take an irresponsible attitude towards everything.
Among other things, we have to remember that these cartoons were not created for children. What they portray requires some knowledge of world history and culture. As it is, I've long considered it honorable that these cartoons could teach children about classical music (much like "What's Opera, Doc?" could).
All in all, a very enjoyable cartoon short.
