Place it right after the mistake in your edit, following Sudden Suspense to build the moment, then follow it with Nelson's Ha-Ha for the payoff. Keep it as the single reaction beat between the setup and the laugh, so the edit moves from tension to failure to mockery without crowding the scene.

This is a very short human vocal clip, lasting under half a second, built around a single sharp 'agh' groan. It sounds like an instant burst of frustration, the kind of noise someone makes when a plan falls apart or a small mistake lands badly. The clipped delivery makes it feel blunt, exasperated and funny, landing as a quick comic sigh rather than a full complaint.
