“Contrary to popular belief and hope, people don't usually come running when they hear a scream. That's not how humans work. Humans look at other humans and say, 'Did you hear a scream?' because the first scream might have been you screaming inside your head, or a horse backfiring.”

“Rincewind could scream for mercy in nineteen languages, and just scream in another forty-four.”

“I staggered into a Manchester bar late one night on a tour and the waitress said "You look as if you need a Screaming Orgasm". At the time this was the last thing on my mind...”

“The merest accident of microgeography had meant that the first man to hear the voice of Om, and who gave Om his view of humans, was a shepherd and not a goatherd. They have quite different ways of looking at the world, and the whole of history might have been different. For sheep are stupid, and have to be driven. But goats are intelligent, and need to be led.”

“The boldest of the three (thieves) moved suddenly, grabbed Angua and pulled her upright. "We walk out of here unharmed or the girl gets it, all right?" he snarled. Someone sniggered. "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.”

“It was lonely on the hill, and cold. And all you could do was keep going. You could scream, cry, and stamp your feet, but apart from making you feel warmer, it wouldn’t do any good. You could say it was unfair, and that was true, but the universe didn’t care because it didn’t know what “fair” meant. That was the big problem about being a witch. It was up to you. It was always up to you.”

“If you don't know when to be a human being, you don't know when to be a witch.”
