Popeye originated in E. C. Segar’s comic strip before becoming the star of animated theatrical shorts produced by Fleischer Studios beginning in 1933. The cartoons established his famous spinach-powered bursts of strength and used lively music to underscore fights and transformations. Popeye’s signature song, “I’m Popeye the Sailor Man,” was written by Sammy Lerner for the animated series. Short musical cues associated with his spinach scenes later spread through television reruns and online edits, where they remain shorthand for an instant, humorous power boost.
