Huck Finn, Chapters 19 - 21

So I'm pretty sure the page numbers I've been giving you haven't been terribly useful. Sorry 'bout that. I grabbed a different copy of the book this morning, so tomorrow's post will have page numbers that ought to match your texts.

1. What did the Duke and the Dauphin do to get in trouble before they met Huck?
2. When do you first realize the Duke is lying about his past?
3. At the end of chapter 19, Huck tells the reader that he knows the Duke and the Dauphin are lying. What is the effect of revealing that information so early? 
4. Do you agree with Huck's advice at the end of chapter 19? In what contemporary situations would it be applicable (or inapplicable)?
5. Compare and contrast the King's "repentant pirate" scene with Pap's rehabilitation in chapter 5. Does the second scene merely reinforce the theme of the first or does it add something new?
6. Is there any difference between Huck's lies and the lies of the Duke and the Dauphin?
7. Why is the Hamlet soliloquy funny? Who is Twain mocking?
8. How does Twain's description of the town prepare the reader for the events that follow?
9. Who is the villain in chapter 21?
