- Teatime's first appearance hints that he's the perfect person to take out Not-Santa. The very first thing he does on the page? Sneak into someplace undetected through the chimney.
- When Violet tells Bilious she's a member of Offler's League of Temperence, Susan reasons that it makes sense that Offler's followers would forego alcohol, as crocodiles don't go into bars often. There is a fairly well-known joke about a man walking into a bar with a crocodile under one arm, but considering how it's not a drink that's put in the reptile's mouth, it makes sense that it wouldn't want to go there voluntarily...
- The not-so-Good King Wencelas whom Death-as-Hogfather confronts is seen forcing a profoundly embarrassed and ashamed woodcutter to accept some Hogswatch charity in the form of the leftovers from his feast. In other words, by "giving" something in a way that causes such distress in the recepient, the king is committing an anti-crime.
- The Analogy Backfire when Teatime declares himself to be a guard's worst nightmare is framed as a joke, but in hindsight it makes some sense for him to take Teatime literally: that's actually what the tower's defenses are.
- The boogeyman at the start of the book asks Susan if she's a witch. Susan doesn't give it a name, but she uses textbook Headology to protect her charges. One of the witch books says that if a man thinks that monsters are after him, a psychologist would persuade him that monsters don't exist, and a headologist would give him a large stick and a chair to stand on. Susan knows there's no point in persuading children that monsters don't exist because they know they do, so she taught them that monsters can be defeated.
- Susan laments the creation of what Miss Tick calls Prohibitive Monsters—monsters adults make to prevent children from performing certain actions. The ones Susan encounters are largely pointless; they punish children for stepping on cracks, sucking thumbs, or writing with their left hands. But in Wee Free Men, Miss Tick's example is Jenny Greenteeth, who was made to prevent children from drowning in ponds. The first Boogeyman doesn't just protect children by taking their teeth. He is the first Prohibitive Monster, and he protects children by making them afraid of dangerous places—especially dark places.
