Place it as the punchline after a straight-faced setup, then follow it immediately with a funny laugh and a Ba Dum Tss drum sting to sell the joke. Keep it as a single hit in a short edit, and pair it with an air horn only when the scene needs a bigger second gag.
About this sound
This is a short fart sound, lasting about 1.3 seconds, presented as the twenty-first entry in the Shitty Jim series. The single loud burst is blunt and unmistakable, with no speech or music around it. It feels crude, silly and deliberately gross, the kind of noise that gets an instant laugh or a disgusted groan from anyone nearby.
