The line comes from Les Visiteurs, the 1993 French comedy in which Christian Clavier plays Jacquouille la Fripouille, a medieval servant brought into the twentieth century. Thrown into a modern world he does not understand, Jacquouille reacts to everyday sights with loud, old-fashioned astonishment, and this short exclamation has become one of his most recognisable moments. Shared on soundboards and in short online videos, it survives because French audiences know the character instantly and because the exaggerated delivery works even for viewers who have never seen the whole film.
