Place it just after a reveal or a sudden scare, then follow it with the Dun Dun Dun sound for a heavier payoff before the scene moves on. Save the Metal Pipe Clang for a sharp interruption later, so the laugh keeps its own moment and the edit does not crowd two shocks together.

This short clip is a single creepy laugh lasting about four seconds. It takes a familiar human laugh and makes it feel wrong, creating an eerie, uncomfortable tension that makes a listener glance over their shoulder rather than smile. It suits moments where the humour comes from discomfort, not from a clear joke.
