Place it near the end of a short fail sequence, just after the mistake lands and before the next clip starts. Pair it with a cartoon fail sting for a bigger payoff, or follow it with an awkward moment cue when the joke needs to linger a little longer.

This is a very short spoken oh from asdfmovie, lasting under a second, delivered in a flat, deadpan voice with almost no build-up. It lands as a small, awkward beat of realisation, funny because it sounds so resigned rather than dramatic. The clip comes from the asdfmovie animated shorts, where brief voices and sudden punchlines carry the joke.
