Sure, you've seen classic WWII propaganda cartoons before. We've all probably watched the Donald-Duck-in-Nazi-land to death. But this is a rarer one, from the cheeky, loopy, surreal animation of Tex Avery. All the staples of Avery are there - fourth-wall-breaking post-modern sign gags, wolf whistles at a girly magazine, literal listening devices made out of giant ears that would tickle Salvador Dali, and improbably gag weapons.
Oh, and unfettered racism, nationalism, and jingoism. And buy some more war bonds, dammit!
