Place it after the reveal in a fail compilation, not under the build-up. Follow a miss with the mission failed sound button first, then let this laugh take the closing beat, or reverse that order after a bad pun with a ba dum tss sound button underneath.

This is a four-second clip of Melvin delivering an exaggerated, wheezing laugh, stretched out longer than a normal chuckle. It feels gleefully mocking and a little unhinged, the kind of cackle that turns a small win or a friend's mistake into a big joke. The laugh comes from MerkMusic's Melvin material.
