These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: Feet of Clay
Bile Fascination: Nobby gets this from high society. One of the nobs describes it as him having "charisn'tma".
Memetic Badass: One of the first examples of Vimes' status as such. Nobby, offered the chance to be King and Vimes' boss, can only worry about the fact that "Vimes will go spare."
Moral Dissonance: After Dorfl is given his freedom he goes around the city visiting ironic retribution on former employers including, at one point, shoving an apple into an apprentice's rear at a butcher's shop. Angua finds it hilarious, ignoring that even if they're following the argument that it's not different from what the people there did to animals, it's still extremely painful and actually dangerous.
Obfuscating Stupidity: Is Carrot really as naive as he lets others believe him to be or has he begun to discover his hidden Manipulative Bastard? Near the end of the book Carrot and Angua have a hilarious One Dialogue, Two Conversations, during which he convinces her to stay in the city, even though she had made up her mind to leave. He appears to be his usual Adorkable self, but Angua instinctively believes that this is not the case. Angua's "feelings" are rarely, if ever, doubted. Moreover, despite the fact he is a major character in this book, chapters that are narrated from his PoV concern the investigation and his thoughts about golems; they do not elaborate on his day-to-day thoughts, like Men at Arms did. He's still an idealist but, as it was mentioned there, simple does not mean stupid.
