Place it immediately after the fail or reveal in a short edit, following a Cartoon Slip for the mishap itself and letting a Nelson Ha Ha answer it, so the second reaction lands after the first instead of competing with the action on screen.

This twelve-second clip is a high-pitched, escalating human laugh that starts with quick breathy hihihi giggles and breaks into louder, almost uncontrollable hahaha bursts, with sharp intakes of breath between them. It feels playful, manic and contagious, lifting a silly moment into something absurd and making listeners smile or laugh along before they know why.
