Place it right at the punchline reaction point in your edit, after the joke setup and before the cutaway response. Pair it with the Woody Woodpecker Laugh for a real laugh contrast, or follow it with a sad reaction sound to underline the flop.

This clip is a short spoken line lasting about two and a half seconds, where a voice delivers the words haha thats very funny in a flat, drawn-out way. It gives off a dry, sarcastic feeling, like polite laughter used to signal that a joke was not actually funny at all to the listener hearing it.
