Place it right after the reveal in a short edit, with Sudden Suspense building tension just before it and Nelson's Ha-Ha! following as the next reaction. Keep it as the payoff beat between the setup and the reaction shot, then cut straight to the next scene.

This clip is a brief 1.3-second human chuckle built from four soft, repeated 'fu' sounds delivered in a low, sly tone. It lands as smug, teasing amusement, the sound of someone quietly pleased with a small trick or a joke that has just landed. It feels playful rather than loud, making it easy to picture a knowing grin behind it.
