Kickin' the Conga Round
Fleets of Stren'th
Navy sailor Popeye is on a battleship. He is in class to learn artillery, but it is way too technical for him; when he gets his hands on the gun, he fires everywhere, including at his own ship. That gets him banished to the boiler room. A real Japanese submarine comes along and the other sailors cannot handle it, so Popeye eats his spinach and dives in to fight the submarine by hand.
