I tell naught but the Truth. Sometimes I tell a Truth And A Half, or even Two or Three Truths all at once. But I communicate ONLY the Truth.

Truth is the silliest thing under the sun. Try to get a living by the Truth, and go to the Soup Societies. Heavens! Let any clergyman try to preach the Truth from its very stronghold, the pulpit, and they would ride him out of his church on his own pulpit bannister.
                               --Hermann Melville

...all through my life my facts have had a substratum of truth, and therefore they were not without value. Any person who is familiar with me knows how to strike my average, and therfore knows how to get at the jewel of any fact of mine and dig it out of its blue-clay matrix. My mother knew that art. When I was seven or eight ...a neighbor said to her, "Do you ever believe anything that that boy says?" My mother said, "He is a well spring of truth, but you can't bring up the whole well with one bucket. I know his average, therefore he never deceives me. I discount him thirty per cent for embroidery, and what is left is perfect and priceless truth, without a flaw in it anywhere."
                                  - Mark Twain's Autobiography

Truth is stranger than fiction, but it is because Fiction is obliged to stick to possibilities. Truth isn't.
