The melody comes from Super Mario Bros, released by Nintendo in 1985, with its theme composed by Koji Kondo and now one of the most recognised tunes in video games. Recorder versions became popular online because the instrument is cheap, widely taught in schools and easy to play by ear, so amateur covers spread across YouTube, TikTok and soundboards as a nostalgic joke. This clip captures that homemade style, keeping the tune instantly recognisable while sounding deliberately less polished than the original game music.
