Place it just before the reveal in a short edit, then follow it with a Vine Boom for the impact and a Dun Dun Dun for the aftermath, letting each clip mark a new beat in the same joke.
O tym dźwięku
This ten-second clip is a single voice repeating oh oh oh in a rising, dawning tone, each repeat landing a little heavier than the last. It gives listeners the comic dread of watching a mistake unfold in slow motion, funny because the speaker already knows how it ends. It works as a pure reaction, with no music or other effects behind the voice.
