[chapter 27] With what bit of dark humor does Twain begin this chapter>?

Huck hides the sack of money in Peter Wilks’s coffin as Mary Jane, crying, enters the front room where her dead father’s body lies. Huck, who doesn’t get another opportunity to remove the money safely, worries about what will happen to it. The next day, a dog barking in the cellar disrupts the funeral. The undertaker slips out and returns after a “whack” is heard from downstairs. In a voice that everyone present can hear, he whispers that the dog has caught a rat. In the next moment, though, Huck watches with horror as the undertaker seals the coffin without looking inside. Huck realizes he will never know whether the duke and the dauphin have gotten the money back. He wonders if he should write to Mary Jane after he has left town to tell her to have the coffin dug up.
