Place it just after the reveal or mistake in your edit, before the next scene starts, then follow it with Oh My God Wow for a second reaction before the punchline lands.
O tym dźwięku
A very short reaction clip lasting about 1.25 seconds, centred on the exclamation Boze Muj. It lands as a quick burst of disbelief and exasperation, the kind of sound that makes a failed plan or an unbelievable moment feel funnier. It works best as a sharp, human reaction rather than a long explanation.
