I would have liked to see it keep going. Like, she just keeps laughing maniacally for like an hour as the rest of the audience quiets down and becomes increasingly concerned, unsure of what to do next.
See, I came not knowing there was a catalyst. I thought she was just going to start laughing for no reason. But her laugh makes up for the cause... by far.
I actually thought this was pretty endearing, but that may just be because I've been known to develop uncontrollable laughing fits myself from time to time.
