"As flat as a flannel-cake, and called Summit, of course," from "The Ransom of Red Chief" by O. Henry, this quote employs the basic usage of a common literary element, irony. The contradiction between the description and the name of the city for the setting of the story, promotes the use of irony, but is not altogether necessary for the story's plot. This is unlike "The Interlopers" by Saki and "The Short Happy Life of Francis Macomber," by Earnest Hemmingway which both require the setting to establish situational irony. If both stories had different settings, they would have never been able to take place and never lead to the protagonists' demises.
In Saki's, "The Interlopers" he makes use of both verbal and situational irony. Throughout the story it is apparent how the setting, in a forest during a windy night, supports situational irony.

Then finally, in the last line of the story, it becomes clear to the reader that the actual "interlopers" are Georg, Ulrich, and their men, they have been trespassing on the "wolves[ ']" forest. The end of the story also contains verbal comic relief irony when "both men raised their voices in as loud a shout as they could muster" thinking they were ...
