Place it at the end of a talking-heavy segment as the final reaction, then follow it with awkward crickets to let the conversation stall on screen, or a chipmunk laugh if another character breaks first and reacts for the group.

This clip is a just over two-second gruff Viennese shout from Mundl, built around Goschn, local slang for mouth, delivered as a blunt order to stop talking. It feels funny and exasperated rather than truly angry, with the directness doing the comedy. It comes from Edmund Sackbauer in the Austrian series Ein echter Wiener geht nicht unter.
