Bluto is being drafted to be in the navy. I love it when he gets the letter: 'who do I know that can write?'. But he really doesn't feel patriotic and when he comes to the office of navy draftsman Popeye he acts like he's unfit to join. When that doesn't work he tries to be hurt in several ways so he won't have to go into the navy.
But things complicate as he sees Popeye being kicked around by some Japanese, and without thinking (literally) he helps Popeye defeat them (but not without the help of the well-known spinache), and finally signs in anyway.
Pretty decent propaganda with some good humour, though there have been better. I'd like to give it a 6/10.
