“Sam Vimes could parallel process. Most husbands can. They learn to follow their own line of thought while at the same time listening to what their wives say. And the listening is important, because at any time they could be challenged and must be ready to quote the last sentence in full. A vital additional skill is being able to scan the dialogue for telltale phrases such as "and they can deliver it tomorrow" or "so I've invited them for dinner?" or "they can do it in blue, really quite cheaply.”

“Everyone says it's going to be Snapcase at the palace. He listens to the people.""Yeah, right," said Vimes. And I listen to the thunder. But I don't do anything about it.”

“There’s lots of people will help you with alcohol business, but there’s no one out there arranging little meetings where you can stand up and say, ‘My name is Sam Vimes and I’m a really suspicious bastard.”

“That's a nice song," said young Sam, and Vimes remembered that he was hearing it for the first time. "It's an old soldiers' song," he said. "Really, sarge? But it's about angels." Yes, thought Vimes, and it's amazing what bits those angels cause to rise up as the song progresses. It's a real soldiers' song: sentimental, with dirty bits. "As I recall, they used to sing it after battles," he said. "I've seen old men cry when they sing it," he added. "Why? It sounds cheerful." They were remembering who they were not singing it with, thought Vimes. You'll learn. I know you will.”

“There was no universe, anywhere, where a Sam Vimes would give in on this, because if he did then he wouldn't be Sam Vimes anymore.”

“The reason that the rich were so rich, Vimes reasoned, was because they managed to spend less money.Take boots, for example. He earned thirty-eight dollars a month plus allowances. A really good pair of leather boots cost fifty dollars. But an affordable pair of boots, which were sort of OK for a season or two and then leaked like hell when the cardboard gave out, cost about ten dollars. Those were the kind of boots Vimes always bought, and wore until the soles were so thin that he could tell where he was in Ankh-Morpork on a foggy night by the feel of the cobbles.But the thing was that good boots lasted for years and years. A man who could afford fifty dollars had a pair of boots that'd still be keeping his feet dry in ten years' time, while the poor man who could only afford cheap boots would have spent a hundred dollars on boots in the same time and would still have wet feet.This was the Captain Samuel Vimes 'Boots' theory of socioeconomic unfairness.”

“Vimes took the view that life was so full of things happening erratically in all directions that the chances of any of them making some kind of relevant sense were remote in the extreme. Colon, being by nature more optimistic and by intellect a good deal slower, was still at the Clues are Important stage.”
