What rhetorical device is used in this excerpt from Mark Twain's "The Danger of Lying in Bed"?

The answer would be anecdote. Allusion is a reference to another work. a rhetorical question is a question that requires and does not want and answer. an anecdote is a brief story designed to illustrate something. logic is how some one using reason to come to a sound/valid conclusion. A n anecdote is not so strict on content. The content of the anecdote is logic reasoning. It could just as easily have been an anecdote for something like irony.
