Put it at the very end of a short setup, just after the line that sets up the embarrassment, then cut straight to a reaction shot. Pair it with the Classic Fart Sound for a bigger gag, or follow it with the SpongeBob Fail Sound when the joke falls flat.
Über diesen Sound
This is a short fart sound effect, lasting under a second, with a single wet, sputtering burst that sounds deliberately crude and over the top. It lands as gross and funny at once, the kind of noise that makes a room groan and then laugh, especially when it catches someone off guard. The clip is the tenth fart in the Shitty Jim series.
