The line comes from Super Mario 64, released for the Nintendo 64 in 1996, during the boss fights where Mario grabs Bowser by the tail and throws him. Charles Martinet voiced Mario, and his energetic goodbye was widely misheard by players for years. The mishearing spread through forums, YouTube remixes and meme edits in the 2000s and 2010s, becoming one of the most quoted Mario jokes online. It remains popular because the original scene is iconic and the phrase works for any farewell.
