Jingle Bells, Batman Smells is one of the best-known playground parodies of Jingle Bells, the Christmas song written by James Lord Pierpont in 1857. The exact origin of the Batman version is unknown, but the rhyme has been passed around schoolyards for decades, with children swapping in new verses about superheroes and pop culture figures. It spread far beyond the playground as the internet turned it into a recurring joke in memes, videos and holiday edits, and short sung clips like this one keep it alive as a quick dose of Christmas-season mischief.
