Place it at the reaction beat, right after the reveal in your edit. Build the moment with an awkward moment sound button first to hold the tension, then use this clip as the release, and follow it with a quick eh eh ehhhh sound button if the joke needs a second tag.

This clip is a short burst of a man's unmistakable, rolling laugh, lasting just under four seconds and carrying the whole moment on that one vocal performance. It feels gleefully over the top and instantly contagious, the kind of laugh that makes a silly situation feel even funnier and turns a listener's straight face into a grin.
