- Growing the Beard: As stated on the main page, Guards! Guards! is often considered the best Discworld book to start new readers on. This was arguably the novel that really codified the Discworld, particularly it's most important setting, Ankh-Morpork.
- Hilarious in Hindsight: A few examples, including the offhand mention of Vetinari's aunt, who says no to being chained up as an offering to the dragon. In Night Watch she's introduced, as a brilliant schemer and extremely forceful personality who, among other things, punched Nobby's lights out. In other words, whoever had to ask her was going to have a really bad time of it. There's also the fact that Sybil's first words to Vimes are "Do you know anything about mating" and he's completely baffled, but they go on to get married and have a son.
- Magnificent Bastard: This is the novel which really creates the character of Vetinari in this way.
"Never build a dungeon you cannot get out of".
- The Dragon itself might be a lesser example.
