Ratz is a French animated comedy series that first aired in 2003, following rats Rapido and Razmo who live aboard a cargo ship full of cheese. Rapido is the taller, self confident half of the duo, which makes his short merci line easy to lift out of context. Clips and voice lines from the show later circulated on soundboards and in fan edits, where this one became a compact reaction for gratitude with a comic edge. Its French wording makes it recognisable even to viewers who never watched the series.
