Place this clip right after the reveal shot in your edit, then follow it with a huh reaction if the scene needs a second response before moving on to the payoff.
Über diesen Sound
A two-second voice clip of a baffled speaker asking what in the hay something is supposed to mean, delivered like a polite stand-in for swearing. It lands as pure bewilderment, funny because the confusion sounds so earnest and thrown, the kind of stunned disbelief you feel when something makes absolutely no sense at all.
