“Over the centuries, mankind has tried many ways of combating the forces of evil... prayer, fasting, good works and so on. Up until Doom, no one seemed to have thought about the double-barrel shotgun. Eat leaden death, demon...”

“The fact was that, as droves of demon kings had noticed, there was a limit to what you could do to a soul with, e.g., red-hot tweezers, because even fairly evil and corrupt souls were bright enough to realize that since they didn't have the concomitant body and nerve endings attached to them there was no real reason, other than force of habit, why they should suffer excruciating agony. So they didn't. Demons went on doing it anyway, because numb and mindless stupidity is part of what being a demon is all about, but since no one was suffering they didn't enjoy it much either and the whole thing was pointless. Centuries and centuries of pointlessness.”

“He was trying to conjure up a succubus." It should be impossible to leer when all you've got is a beak, but the parrot managed it. "That's a female demon what comes in the night and makes mad passionate wossn-""I've heard of them," said Rincewind. "Bloody dangerous things."The parrot put its head on one side. "It never worked. All he ever got was a neuralger.""What's that?""It's a demon that comes and has a headache at you.”

“Cards and boards, [Johnny] thought. And the dead. That's not dark forces. Making a fuss about cards and heavy metal and going on about Dungeons and Dragons stuff because it's got demon gods in it is like guarding to door when it is really coming up through the floorboards. Real dark forces... aren't dark. They're sort of gray, like Mr. Grimm. They take all the color out of life; they take a town like Blackbury and turn it into frightened streets and plastic signs and Bright New Futures and towers where no one wants to live and no one really does live. The dead seem more alive than us. And everyone becomes gray and turns into numbers and then, somewhere, someone starts to do arithmetic...”

“Oh, well...up until now it had been a good day, in a horrible kind of way.”

“You are very clever," said the old man shyly. "I would like to eat your brains, one day."For some reason the books of etiquette that Daphne's grandmother had forced on her didn't quite deal with this. Of course, silly people would say to babies, "You're so sweet I could gobble you all up!" but that sort of nonsense seemed less funny when it was said by a man in war paint who owned more than one skull. Daphne, cursed with good manners, settled for "It's very kind of you to say so.”

“The brain works fast when it thinks it’s about to be cut in half.”
