Place it immediately after the impact in a fail edit, then follow it with Emotional Damage to turn the complaint into a punchline. If the moment needs a second beat, use Bruh as the next response, letting the two responses carry the joke without another effect.
About this sound
This ten-second Portuguese voice clip has Salsicha yelping 'Ai, a minha perna!' after hurting his leg, with the panic and over-the-top pain in his voice doing most of the work. It feels goofy and sympathetic at once, like a cartoon injury played for laughs rather than real harm. The line comes from the Brazilian Portuguese voice of Scooby-Doo's Shaggy.
