This reminded me of several cartoons where the writers would go back and have one scene each about different fairy tales and then use a joke for each. In here, instead of old fables, we get a travelogue where the narrator explains where we are, and then you get one (usually very corny) joke for each location. At the end, Bugs Bunny makes a cameo appearance, with a plug for the World War II effort, but this is not a Bugs cartoon.
We begin in the Old South at a tobacco farm where we learn the dangers of the boll weevil and that bug is the joke. Oddly, they show a map to their next destination and we see line going from Florida (around where Naples is located) to Havana. A tobacco area in Florida? Talks about "goofs."
Most of the jokes in here are really stupid, not funny, to be honest. I doubt many people today would laugh at this stuff. I did enjoy one bit of narration in which narrator Robert Bruce comments, "Continuing our journey, we push into the Congo, past the Samwabi swamplands, over the Gondoogi mountains, across the Rag-a-nack River.....and then we visited Veronica Lake (whistle)."
(Well, if that's the best of the jokes, you get an idea how bad most of this is!)
A warning to black readers: there is a racist gag near the end then they travel in a jungle area. At least Mel Blanc enters the cartoon with some voices.
Overall, as mentioned, this was like the "fairy tale" vignettes cartoons which means they kept it interesting by changing subjects quickly but the jokes are too lame. I can't believe audiences even laughed at this 45 years ago. Not recommended.
