- Genius Bonus:
- Yes, Sir George Cayley and his attempts at heavier-than-air flight are real.
- The scene where Dodger has his caricticure drawn by John Tenniel for Punch has a bit more resonance when you know that Tenniel probably also drew the caricticures on Simplicity's Happy Families cards.note
- One subtler reference to Oliver Twist. Oliver Twist had a character rather controversially known as Master Bates. Onan the dog is named after the biblical figure who lends his name to onanism, a word meaning rather the same thing as "Master Bates".
YMMV / Dodger
