Place it immediately after the reveal in an edit, then follow with Nelson's Ha-Ha for a bigger laugh, or lead into it with Sudden Suspense to build tension before the payoff.

This is a short, under-a-second burst of repeated hehe laughter, delivered as a quick, breathy giggle that sounds sly rather than loud. It feels playful and mischievous, like someone caught in a joke or quietly enjoying a small win, and it lands best as a light teasing reaction instead of a big laugh.
