Here are some quotes from the disc:
Patrician: I'm going to introduce a new tax. Per capita as the lawyer say and if you don't like per capita, I can happily arrange decapita. In a democracy, everyone gets treated the same.
Ankh-Morpork had dallied with many forms of government and had ended up with that form of democracy known as One Man, One Vote. The Patrician was the Man; he had the Vote.
He did of course sometimes have people horribly tortured to death, but this was considered to be perfectly acceptable behaviour for a civic ruler and generally approved of by the overhelming majority of citizens. [footnote: The overhelming majority of citizens being defined in this case as everyone not currently hanging upside down over a scorpion pit]
There were no public health laws in Ankh-Morpork. It would be like installing smoke detectors in Hell.
All dwarfs are by nature dutiful, serious, literate, obedient and thoughtful people whose only minor failing is a tendency, after one drink, to rush at enemies screaming "Arrrrrrgh!" and axing their legs off at the knee.
