The clip comes from Monty Python and the Holy Grail, released in 1975, where a procession of monks chants Pie Jesu Domine, dona eis requiem while hitting themselves with boards. The scene parodies medieval religious processions seen earlier in films like The Seventh Seal. Clips and audio rips circulated on early soundboards and later in YouTube edits, gaming videos and meme compilations. Its mix of genuine plainsong delivery and slapstick violence made it a shorthand for overly serious rituals, which is why creators still reuse it decades after the film.
