Place this laugh at the very end of a sequence as the final reaction. Lead into it with a sudden suspense sting while the plan is revealed, then follow with Nelson's Ha-Ha! if you want a second laugh layered as the outro.

This clip is a short burst of Chuggaaconroy delivering an exaggerated maniacal laugh, all cackling voice and rising intensity over about two seconds. It feels gleefully unhinged and startling in a funny way, like a cartoon villain who is far too pleased with himself and wants everyone else to hear it.
