Place this clip at the very end of a fail compilation, after the mistake has already landed, then follow it with Nelson's Ha-Ha! for a mocking second laugh and close on the Laughing Dog Meme to turn one bad laugh into a whole chorus.

This clip is a roughly eight second recording of a person bursting into a loud, wheezy, completely unpolished laugh that keeps going past the polite point. It sounds like someone laughing at themselves as much as at anything else. The feeling is awkward and infectious at once, the cringe of hearing your own cackle played back and finding it funnier than the joke.
