The names come from the 1993 live-action Super Mario Bros. film, where Mario and Luigi are given the shared surname Mario, making Mario Mario and Luigi Mario. The gag survived long after the film because it neatly explains why the brothers share a name while sounding deliberately silly. Clips of the line circulated among Mario fans and meme editors, who reuse it whenever the characters appear together. Its short length and instantly recognisable setup keep it useful for introductions, jokes about the film, and playful nods to Nintendo history.
