Pig: Hey, Goat...what does it take for a book to become known as great literature?
Rat: It has to both bore and confuse everyone.
Rat: Except for high school English teachers. They have to like it.
Pig: What's wrong with those people?
Hemingway, Steinbeck, and “Catcher in the Rye” are neither boring or confusing and they are great literature.
