Place this clip at the peak of the reaction shot, after a dun dun dun sound button builds the suspense and before a vine boom sound button closes the gag, so the sequence rises, peaks, then resolves.
Über diesen Sound
This clip is a female scream lasting under a second, with the pitch shifted into a G Major effect that makes the voice sound warped and exaggerated. It feels startling and absurd at the same time, turning a moment of panic into something funny rather than frightening, especially because the scream is so brief and over the top.
