Matt was talking about Armaggedon and it reminded me of this excerpt from Gaiman/Pratchett's Good Omens:
Crowley (the demon) was ruminating:
That's how it goes, you think you're on the top of the world, and suddenly, they spring Armaggedon on you.. The Great War, the Last Battle.. That's what the end of the world meant. No more world. Just endless Heaven, or, depending who won, endless Hell.
Crowley didn't know which was worse.
Well, Hell was worse, ofcourse, by definition. But Crowley remembered what Heaven was like, and it had quite a few things in common with Hell. You couldn't get a decent drink in either of them, for a start.
And the boredom you got in Heaven was almost as bad as the excitement you get in Hell.
