Place it after the visual gag lands, not before, so the reaction carries the scene. Follow it with Nelson's Ha-Ha! for a mocking second beat, or precede it with a laughing dog meme button when you want the laughter to build across two different reactions in one edit.

This clip is a man's sustained laugh lasting just under eight seconds, with the chuckling building in waves rather than stopping after a single burst. It feels gleeful and a little over the top, the kind of unrestrained laughter that makes a funny moment feel even funnier and turns a mild reaction into pure amusement for everyone listening nearby.
