Dramatic irony is when the
characters are oblivious to something that the audience knows. This
understanding among the audience makes the dialogues of the characters have a
different meaning that creates humor or suspense.
Mark Twain portrayed the
role of a deadpan narrator who had no idea that his narration was humorous. His
ignorance or innocence made the audience laugh. He further makes them laugh by saying whether the audience was tickled by what he had said.
