The FBI busts the bizarre orgy and issue arrests. The monkey's mom is being tried for negligence. Riddler is being held indefinitely by the US government for further questioning. McDonald's issues a public apology for its clown's behavior, and fires it's entire advertising department.
Suddenly, absolutely nothing happens. Shortly afterward, the sky split. There was a rather ghastly tear in the middle of it, it hurt your eyes to look at it for more than a few moments. The tear wasn't the worst bit, it was what was on the other side of it.
Righteous crusaders of order and reason arrive and rain holy fire down upon the land. The sinners are damned to hell forever, dragged to eternal tournament by none other than an annoyed looking Fred Phelps. The four horsemen gallop across the land (or what was left of it anyway, most of the land inexplicably transformed into indescribable anomalies of exotic matter), ruining crops, bringing death, war, and plague. These, however happened to be the least of everyone's worries. The atmosphere seemed to have gone missing* and the threat of mass global extinction from asphyxiation was a bit more pressing. You can guess what happens next. Every culture has a story, some being comes and cleans up the mess, starts a new world.
In this case, the Janitor of the Ages arrives on cue. Rather anticlimactic when you think about it, all the lore indicates otherwise. Stories predating humanity itself speak of ancient gods running about, with the very laws that hold the universe together going on holiday. A rather unremarkable and unshaven man checks his ancient pocket watch, waits a few moments, and starts sweeping. And there is a lot of sweeping to be done...
*It might seem like an odd think for the atmosphere to do, but it actually makes quite a bit of sense. She†probably realized that humans wouldn't be needing her for much longer anyway, and went some place pleasant, like the beach. Obviously not a beach on the Earth though.
†It's a commonly accepted fact that the atmosphere is female. It was first discovered in 462BC by the ancient and knowledgeable monks of what is now 39th Street, East Chicago, between that quaint bookstore and that little French cafe that serves tea on paper doilies. However, to this date, forensic archaeologists have been unable to find what tool was used by the monks that led to the discovery.
