Place it immediately after the failed moment in your edit, then follow it with Nelson's Ha-Ha! for a cartoon-style echo, or switch to Sad Violin for mock sympathy once the reaction has passed.
About this sound
This clip is a short burst of repeated human laughter, six quick ha sounds in a row lasting just over three seconds. The voice is bright and exaggerated, with each ha landing in a steady, rhythmic pattern that makes the laugh easy to recognise instantly. It feels playful and teasing, like someone laughing at a clumsy mistake, and it lands as light mockery rather than cruelty.
