Place it immediately after the suspicious claim or offer, then follow it with Zu Risiken und Nebenwirkungen for a second German line, or cut to You What when you want the doubt to land harder. Keep it as the punchline of the exchange, not as background.
O tym dźwięku
The clip is a short German spoken line from Arno Dübel, lasting about four seconds, delivered in his flat, matter-of-fact voice as he says the phrase in the title. It feels dryly amused and slightly smug, like a small compliment offered with a knowing pause. That deadpan delivery makes the line land as a wry reaction rather than a straightforward remark.
