Place it after the visual payoff, not over the set-up, then follow it with the cat laugh meme button for a second laugh layer or swap in the baby laughing meme button when you want a cuter closer before cutting away.
About this sound
This is a short three-second voice clip built from repeated ha ha ha laughter that rises into drawn-out uuiii uiii squeals. The shift from normal laughing to that high, silly wheeze is what makes it feel gleeful and a little unhinged, like someone cracking up harder than the moment deserves.
