* FunnyAneurysmMoment: One of the book's themes is Moist's economic argument that relying on gold as a standard is a bad idea. Almost immediately after the book was published, Britain crashed into recession and Prime Minister Gordon Brown was heavily criticised for selling off the country's gold reserves several years before, which would now be worth more than eight times as much.
** To be fair, Moist's argument was that gold as a standard is unnecessary, not bad. Having some lying around for additional capital is not argued as being a bad thing, just that "money" is a lot more complicated than just being worth a certain amount of gold. Still qualifies, though, since Moist was talking about selling the gold to the dwarves...
** It also contains fairly obvious and accurate RealitySubtext: According to Moist, the Royal Bank doesn't have even nearly enough gold to actually back up all of their money, and the chief cashier says that the arrangement of promising the money's worth of gold hinges on no one ever trying to collect on that promise - which happens to be the very reason why the gold standard failed in Real life.
** Also, [[spoiler: selling off the gold too early turns out to be exactly what the ''villains'' had done.]]
* GeniusBonus: Vetinari's argument of Quia Ego Sic Dico (Because I say so) is probably bound to go over the head of most people. Without ready access to a source of information on Latin, it could easily be mistaken for just another ridiculous law that Mr Slant is so fond of quoting.
* MoralEventHorizon: It's one line, and easy to miss, but Cosmo Lavish has someone killed ''over a hat''.
* StealthPun: This one is a bit... involved. When Cribbins' dine-chewers fail for the last time, a spring pierces his cheek, leaving a bloodstain. For Cribbins to think he could out-gambit Moist truly is a bit of bloody cheek on his part.
