Place it at the end of a confused exchange, after the other person's reaction, so the question closes the scene. Pair it with a shocked sound first for the misunderstanding, then let this question follow as the punchline, and finish with a short laugh for a clean payoff.

This is a short spoken clip of a voice asking 'Verstehst du?' in German, lasting just over four seconds. The direct question lands as teasing and a little confrontational, like checking whether someone has really followed what was just said. It works best as a pointed nudge, turning a missed point into a joke without adding any extra explanation.
