What are some examples of humor in "The Cask of Amontillado"?
The first suggestion of humor in "The Cask of Amontillado" occurs when Fortunato makes his first appearance dressed, ironically, as a court jester--a fool.
The man wore motley. He had on a tight-fitting parti-striped dress, and his head was surmounted by the conical cap and bells. I was so pleased to see him that I thought I should never have done wringing his hand.
When Montresor suggests that he should seek out their mutual friend, Luchesi, as a participant instead, Fortunato replies,
"Luchesi cannot tell Amontillado from Sherry."
"And yet some fools will have it that his taste is a match for your own."
Fortunato's cough is of concern to Montresor, and he recommends that the two men go back. But Fortunato must sample the sherry.
"Enough," he said; "the cough's a mere nothing; it will not kill me. I shall not die of a cough."
"True—true," I replied...
Montresor, of course, already knows Fortunato's fate. Montresor mocks Fortunato when he makes a toast "to your long life." Another amusing moment occurs when Fortunato asks for a sign that Montresor is also a membership of the fellowship of Masons: Montresor produces a trowel, the tool of trade for masonry. "You jest," Fortunato tells Montresor, but he will soon see that the last laugh is on him.
