According to a different source, this question refers to the story "The Nose" by Nikolai Gogol.
In this story, the author creates a humorous anecdote about a man who loses his nose. There are several strategies that the author employs in order to create humour in the story.
One of the methods that the author employs is sarcasm. Sarcasm is a sharp remark that employs irony in order to express contempt. The author uses sarcasm when describing almost all the characters in the story.
Another method that the author employs is that of describing situations in extreme detail. By doing this, the author is able to create a vivid image in the mind of the reader. However, this is also effective as it highlights how "pointless" and "small" the concerns of the people in the story are, which creates a humorous effect.
These methods are effective for several reasons. First, they help support the plot, which has the effect of drawing the reader deeper into the story. The methods also create a more vivid image of the characters, the setting, and the events of the story. Finally, these methods make the character's flaws and follies more relatable to the reader, and therefore, funnier.
