Place it right after the reveal of a failed plan, then follow it with the sad violin for the aftermath, or cut to Nelson's Ha-Ha when the failure belongs to someone else. Keep it as the turning point between the setup and the payoff, with a reaction sound before it if the moment needs a build-up.
Over dit geluid
This is a short spoken reaction, just under three seconds long, in which a voice delivers the line 'It's horrible...' in a flat, drained tone. It lands as weary dismay rather than shock, the sound of someone giving up on a situation that has already gone wrong. The line comes from Starbarians - Episode 2.
