Place it after the visual payoff, not before it, so the edit reads as a reaction. Lead in with the cartoon slip for a physical gag, then follow this clip with the Goofy Ahh Running button when the character bolts from the scene.
About this sound
This clip is just under five seconds of deliberately weird, goofy noises strung together, with exaggerated cartoon-like voices and effects that do not sound like anything normal. It feels funny in an awkward, brain-off way, the kind of silly and slightly unhinged energy that makes a normal moment feel completely absurd for no reason at all.
