“Well, I think," said Nobby, "that when you rule out the impossible, whatever is left, however improbable, ain't worth hanging around for on a cold night wonderin' about when you could be getting on the outside of a big drink.”

“Once you've ruled out the impossible then whatever is left, however improbable, must be the truth. The problem lay in working out what was impossible, of course. That was the trick, all right. There was also the curious incident of the orangutan in the night-time.”

“And what do they talk about beyond the barricade, my little lad?”“Um…well, Justice an' Truth an' Freedom and stuff,” said Nobby.“Aha. Rebel talk!” said Carcer, straightening up.“Is it?” said the major.“Take it from me, major,” said Carcer. “When you get a bunch of people using words like that, they're up to no good.”

“We're dealing here," said Vimes, "With a twisted mind.""Oh, no! You think so?""Yes.""But... no... you can't be right. Because Nobby was with us all the time.""Not Nobby," said Vimes testily. "Whatever he might do to a dragon, I doubt if he'd make it explode. There's stranger people in this world than Corporal Nobbs, my lad."Carrot's expression slid into a rictus of intrigued horror."Gosh," he said.”

“There have been times, lately, when I dearly wished that I could change the past. Well, I can’t, but I can change the present, so that when it becomes the past it will turn out to be a past worth having.”

“I want a proper school, sir, to teach reading and writing, and most of all thinking, sir, so people can find out what they are good at, because someone doing what they really like is always an asset to any country, and too often people never find out until it is too late. There have been times, lately, when I dearly wished that I could change the past. Well, I can't, but I can change the present, so that when it becomes the past it will turn out to be a past worth having....Learning is about finding out who you are, what you are, where you are and what you are standing on and what you are good at and what's over the horizon and, well, everything. Its about finding the place where you fit. I found the place where I fit, and I would like everybody else to find theirs." - Tiffany Aching”

“Vimes had once discussed the Ephebian idea of ‘democracy’ with Carrot, and had been rather interested in the idea that everyone had a vote until he found out that while he, Vimes, would have a vote, there was no way in the rules that anyone could prevent Nobby Nobbs from having one as well. Vimes could see the flaw there straight away.”
