“What's a philosopher?' said Brutha.Someone who's bright enough to find a job with no heavy lifting,' said a voice in his head.”

“What sort of person," said Salzella patiently, "sits down and writes a maniacal laugh? And all those exclamation marks, you notice? Five? A sure sign of someone who wears his underpants on his head. Opera can do that to a man.”

“Yes," said the skull. "Quit while you're a head, that's what I say.”

“But is all this true?" said Brutha.Didactylos shrugged. "Could be. Could be. We are here and it is now. The way I see it is, after that, everything tends towards guesswork.""You mean you don't KNOW it's true?" said Brutha."I THINK it might be," said Didactylos. "I could be wrong. Not being certain is what being a philosopher is all about.”

“If they look as though they're worried, we'll move in.''And do what exactly?' said Polly.'Threaten to shoot them,' said Maladict firmly.'And if they don't believe us?''Then we'll threaten to shoot them in a much louder voice,' said Maladict. 'Happy? And I hope to hell they've got some coffee!”

“The librarians were mysterious. It was said they could tell what book you needed just by looking at you, and they could take your voice away with a word.”

"I hope you're not going to kill anyone," said Carrot."That's up to us!""Sorry, was I talking to you?" said Carrot. "Don't worry, I'll be fine," said Angua. She looked around to make sure Cheery wasn't there and then sighed."Come on, gentlemen, let's get this over with.""Don't play with your food!" said a voice from the crowd.There were one or two giggles until Carrot turned in his seat, whereupon everyone was suddenly intensely interested in their drinks."It's OK," said Angua quietly.Aware that something was off kilter, but not quite sure what it was, the thieves edged back to the door. No one moved as they unbolted it and, still holding Angua, stepped out into the fog, shutting the door behind them. "Hadn't we better help," said a constable who was new to the Watch. "They don't deserve help," said Vimes. there was a clank of armor and then a long, deep growl, right outside in the street. And a scream and then another scream. and a third scream modulated with "NONONOnonononononoNO!...aarghaarghaargh!" Something heavy hit the door.”
