I'm in the Army Now

In this one, Olive Oyl is walking down the street with Popeye and Bluto disputing whom she really wants to date. She spots an army recruiting poster and goes gaga. The boys head into the recruiting office. They vie for the one opening spot by opening their scrapbooks, showing clips from their earlier cartoons.

In series television, this would be called a clip show, which is literally one composed largely of clips from earlier shows. In cartooning, its known as a cheater, a way to reduce production costs by repeating a bit of film -- "looping" -- or other means. These techniques reduce the cost of making a production, indicating that the Popeye series was spending more than its budget.
