Place this clip right after the on-screen mistake, then follow it with a classic fart for a callback later in the same scene. If the reaction needs a second beat, layer the fart meme sound underneath the crowd's response before returning to dialogue.
Über diesen Sound
A guy farting for roughly twelve seconds, this clip is a single drawn-out bodily sound effect rather than speech or music. It feels gross, childish and openly funny, the kind of awkward noise that breaks tension instantly and makes a serious moment impossible to take seriously again.
