Snafu complains about being a "dogface" in the infantry. Once he notices a restroom 18,000 miles away, he wishes that he joined the Tank Corps, because "they do their fighting on a nice, soft seat." Technical Fairy appears and promotes him to member in the Tank Corps. Snafu happily rides a tank across bumpy terrain, but finds that he has a hard time controlling it and eventually almost falls off a cliff. Hanging from the main gun of the tank, he wishes that he joined the Navy. The Technical Fairy appears and teleports him to the Navy. Snafu rides a boat through choppy waters until he runs into a wave and comes out riding on two fish. Coughing up water, he says "Give me air!" Technical Fairy teleports him to an airplane in the Air Force. He flies a plane until he runs into a mountain, leaving him in only a cockpit. When Snafu comes to, he finds that he is back in the Infantry. Technical Fairy and Snafu march away, singing to the tune of "Hinky Dinky Parlez Vou" that all the services are tough and any "soldier or gob" should "finish the job."
