Nine-tenths of the value of a sense of humor in writing is not in the things it makes one write but in the things it keeps one from writing. It is especially valuable in this respect in serious writing, and no one without a sense of humor should ever write seriously. For without knowing what is funny, one is constantly in danger of being funny without knowing it.

Robert Benchley (1889-1945) American humorist
