Place it at the exact beat where someone is caught out, after Sudden Suspense and just before Nelson's Ha-Ha lands the mockery. Follow it with Oh My God Wow as the next beat, and save a second embarrassment for later in the same edit.

This is a fart sound effect lasting about nine seconds, long enough to stretch the gag past a quick toot into something deliberately overdone. It feels crude and childish in the best way, the kind of humour that makes people groan, laugh and look around to see who did it. It suits a shameless, in-your-face gag rather than a quiet background joke.
