Place it right after the mistake in your edit, then follow it with an awkward moment for the pause before the next scene. For a bigger fail, pair it with a womp womp fail after the bonk so the joke builds in two steps.

This is a short 1.4-second clip built around two quick bonk sounds, a cartoon-style thump repeated twice for comic timing. It feels silly, light and gently teasing, like tapping someone on the head for a harmless mistake rather than scolding them. The double hit makes it land as a playful joke instead of a harsh sound.
