Place it near the end of an edit, right after the failed moment, then follow it with SpongeBob Sad Song to stretch the joke before cutting away. For a sharper contrast, open with Law and Order Dun Dun and let this clip answer it.
About this sound
This 29-second clip centres on Beast Boy from Teen Titans Go in a sad, downbeat moment, with the cartoon character's low mood doing all the comic work. It feels awkward and gently miserable, like a reaction to bad news, and it works because the sadness is exaggerated rather than serious. The sound comes from the Teen Titans Go television series.
