This is a short German voice clip, lasting about two and a half seconds, in which a speaker delivers the phrase Keine Kapriolen in a firm, clipped tone. It lands as a deadpan rebuke, stern enough to stop the silliness but playful enough to make people laugh at the sudden seriousness. The delivery feels like a teacher or parent calling time on the messing around.
