Put it at the end of a fail sequence, after the mistake and just before the next scene, then follow it with the Homer Ta Gueule sound for a second reaction, or swap in the Woody Woodpecker laugh when you want a different cartoon follow-up.

This under-two-second clip is Nelson Muntz's clipped, nasal 'Ha-ha' from The Simpsons, voiced by Nancy Cartwright. The laugh lands as a sharp, gleeful taunt that turns another person's slip-up into the joke, giving the listener a burst of playful, slightly cruel amusement. It comes from the long-running animated series, where Nelson, the school bully, uses it to ridicule classmates.
