Place it just after the reveal of a bold plan in your edit, then cut to the game show buzzer when the plan fails, and finish with goofy ahh sounds for the reaction shot that closes the scene.
About this sound
This short clip captures Papyrus delivering his signature nyeh heh heh laugh in a bright, theatrical voice. It feels proudly goofy and overconfident, like a villain celebrating a plan that is already falling apart. The line comes from Papyrus, the enthusiastic skeleton from the game Undertale, and it works because his cheerful delivery turns a simple laugh into an instantly recognisable moment of comic self-importance.
