Mighty Mouse began as a Terrytoons cartoon hero in the 1940s, a small superhero mouse who flew in to rescue characters in danger. His theme, best known for the line Here I come to save the day, became inseparable from that last second rescue image. The song was later revived for new generations when Andy Kaufman lip synced it on Saturday Night Live in 1975, cementing it as a comedy reference. Online, creators still reuse the short hook whenever an entrance needs instant, exaggerated hero status.
