While Leonard explains why writers should do away with extraneous sentences, he quotes a character in John Steinbeck's "Sweet Thursday"-
"Sometimes I want a book to break loose with a bunch of hooptedoodle.... Spin up some pretty words mabe or sing a little song with language. That's nice. But I wish it was set aside so I don't have to read it. I don't want hooptedoodle to get mixed up with the story."
