Place this clip right after the visual payoff, then follow it with the baby laughing meme for a longer reaction or the yaaaay cheer before cutting back to dialogue and the next scene in your edit sequence.

This Cocomelon clip is a short 3.8-second burst of a young child laughing in a rapid, sing-song LOL pattern over and over. The giggle is high, bouncy and deliberately over the top, giving listeners a silly, cheerful feeling that turns even a flat moment into something playful and a little bit absurd for everyone who hears it.
