* CanonSue: Nutt. Granted, this might be a result of his story feeling a bit shoehorned in from a different manuscript at times, with all the setbacks and failures removed from there to get the book down to an acceptable length. What's left is a character who succeeds at everything he tries in ways beyond everyone else's abilities. Scene after scene is spent telling the reader about his abilities, how impressed other characters (except the bad guys, of course) are with what he can do and things usually associated with the term 'Mary Sue'. There's an attempt to justify everything and give him self-esteem issues as a flaw, but the justification just opens up more [[FridgeLogic questions]] and the flaw isn't having any actual impact on him. At all.
* HilariousInHindsight: An American distributor (apparently due to a complete lack of understanding of Morris dancing) once claimed ''Discworld/LordsAndLadies'' was about a football team in its synopsis, to which Pratchett's response was that football was one subject he would ''never'' write a Discworld book about...
* OlderThanTheyThink: If the book was intended as a subversion of [[spoiler:Tolkien's conception of Orcs, in fact some of Tolkien's late writings move along remarkably parallel lines, considering that orcs might have free will when apart from their evil masters and being made from ruined men rather than elves. He died before he could finally decide on one definite origin story and cosmic fate]].
** Considering, it's probably more ShownTheirWork...Or FridgeBrilliance.
* SeparatedByACommonLanguage: Evans the Striped's posthumous threat to make boys without their kit [=PLAY IN THEIR PANTS=] went over the heads of American readers who didn't realize he meant their ''under''pants.
* WhatAnIdiot:
** The Librarian [[spoiler: eating the poisoned banana.]] [[JustifiedTrope Justified]] - considering the Librarian's reputation and how everyone else regards him, [[spoiler: who would be stupid enough to try poisoning him with even a sedative?]] And also foreshadowed, much earlier, when it's mentioned that [[spoiler:unlike men, who waste a lot of time asking questions like "I seem to see a banana, but could my senses be deceiving me?", an orangutan will just eat the banana]]. The Librarian's habit of taste-testing anything he happens upon isn't new; it's why he's unofficially banned from the High Energy Magic building.
** Mrs. Atkinson, who [[spoiler: poisoned the Librarian in the first place, having failed to realise that being an old lady with a big vicious son might protect her from retribution in the Shove, but will do nothing to stop the wizards or, for that matter, the angry Librarian himself punishing her.]]
* TheWoobie: Nutt, most of the time. [[spoiler:At least before he tried auto-hypnosis quasi-Freudianism.]]
** A Woobie, for sure, but of the [[IronWoobie iron]] kind.
