I remember seeing this cartoon as a child and I have always enjoyed it. Porky is having trouble learning the Pledge of Allegiance, when he's about to give up, Uncle Sam himself shows up and gives him a history lesson. I like the semi-realistic portrayal of Uncle Sam and the historical figures, though it's nothing like later Looney Tunes and/or Chuck Jones' trademark style. Also, I'm surprised most people don't know that the "Under God" line is a later addition! It was always in heavy rotation around the 4th of July on various syndicated Looney Tunes packages, so I and lots of others my age are very familiar with it.
