Place it right after the funniest moment in an edit, then follow it with a baby laughing meme for a second wave of laughter, or cut to a cat laugh meme when the joke turns absurd. For a failed joke, put an emotional damage meme first so this laugh closes the bit after the cringe.

This is Laercio laughing for just over four seconds, a hearty, unrestrained laugh with no words, just the sound of someone finding something very funny. It feels warm, silly and contagious, the kind of laugh that makes a small joke seem much funnier and is hard not to join in with.
