Place it at the end of a setup about a bargain, then follow it with the Law and Order Dun Dun for a mock-serious verdict, or open with the DJ Airhorn to celebrate the low price before the line delivers the punch.
O tym dźwięku
This is a short spoken line, lasting about 1.7 seconds, in which a single voice states plainly that an idea is cheap. The delivery is flat and matter-of-fact, giving it a dry, slightly dismissive edge that lands as a joke rather than a complaint. It feels like a quick verdict on a low-effort plan, best used when the cost is the whole point.
