Luigi was introduced by Nintendo in the 1983 arcade game Mario Bros as Mario's younger brother and the second player character. Over decades of Super Mario games, Luigi's Mansion and Mario Kart, his timid voice and nervous personality became as familiar as his green outfit. Short character clips like this circulate on soundboards and in fan edits because a few seconds of audio can signal the whole character. The clip remains popular for gaming memes where being cautious, late or overshadowed is the joke.
