Inside every old person is a young person wondering what happened. (p. 263)

Oh, I suppose if you're a powerful merchant it's nice to have a famous wife. It's like owning jewelry. (p. 330)

"They're pretty high mountains," said Azhural, his voice now edged with doubt.

Being trampled almost to death by a preoccupied troll is almost the ideal cure for a person confused about what is real and what isn't. Reality is something walking heavily up your spine. (p. 319)

After all, Ankh-Morpork itself was generally considered as wicked a city as you could hope to find in a year of shore leaves, and seemed to have avoided any kind of supernatural vengeance, although it was always possible that it had taken place and no one had noticed. (pp. 174-175)

Probably only one person in the world had been interested in whether the old man lived or died, and he'd been the first to know. (p. 91)

The machine whirred on, winding reality from the future to the past. (p. 286)

Magic wasn't difficult. That was the big secret that the whole baroque edifice of wizardry had been set up to conceal. Anyone with a bit of intelligence and a bit of perseverance could do magic, which was why the wizards cloaked it with rituals and the whole pointy-hat business. (pp. 178-179)

"Come on," said Gaspode. "It's not right, you being alone in a lady's boodwah."
