Place it at the end of a call gag, just after the punchline lands, then follow it with Nelson's Ha-Ha and later add Laughing Dog Meme when the joke keeps building.

This is a short two-second clip of a bright, repeated aha aha laugh, delivered in a quick burst that feels like someone reacting on a phone call. It gives a playful, teasing feeling, light and knowing rather than loud or mean, and it works best when the humour comes from the timing of the reaction itself.
