The Bug Parade (1941)

A spot gag cartoon based on little-known facts about bugs. A narrator guides us on a tour of the insect world. Each creature we meet surprises us with a funny gag. A snail's shell bears the sign "F.H.A. Loan." Two caterpillars shake hands... lots of hands. There's a humorous reference to Bing Crosby and even a Del Monte brand product placement.
