Place it at the end of a short reaction sequence, after a build-up clip such as Oh My God Wow, so the face becomes the payoff. Follow it with Nelson's Ha-Ha to extend the reaction, or cut straight to the next scene while the reaction is still fresh.
Über diesen Sound
This short spoken clip delivers the phrase 'Your Face!' in under two seconds, aimed squarely at someone's expression in the moment. It lands as a quick teasing jab, funny and a little awkward, the kind of line that turns a surprised look or a failed bluff into the joke itself. It works best as a fast reaction rather than a line to build around.
