Put it at the very end of a clip, after the setup has played out and the twist is visible on screen. Open a fail with SpongeBob Fail, then close with this clip, or follow it with Vine Boom when the joke needs a heavier final hit.

This 2.5-second clip is a cartoon vocal effect that pulls one playful syllable out into a rising, wobbly swoop before letting it fall away. It feels exaggerated and silly, like an overexcited announcement of something absurd, and it lands as a light punchline rather than background noise, instantly telling a listener that a joke, fail or twist has just happened.
