The Laws of Fiction?

What are the laws of fiction?

I've come up with a few on my own:

First law: Never bore the reader.

Fourth law: Monkeys are funny. (Corollary to the fourth law: Talking monkeys are hilarious.)

Fifth law: When in doubt, have one character kick another in the nuts.

Eighth law (Chekhov's Law): "Don't tell me the moon is shining; show me the glint of light on broken glass." --A. Chekhov*

Ninth law: Immature writers create "homages." Mature writers steal.

Fourteenth law: Any character can be improved by making the character talk like a pirate.

Nineteeth law (Steve Martin's Axiom): "I believe entertainment can aspire to be art, and can become art, but if you set out to make art, you are an idiot." --S. Martin

Twenty-second law: Any story can be improved by the addition of monkeys, ninjas, or both.

These aren't just the fevered workings of a dorkish mind. I can prove their validity. Take the twenty-second law, for example. Wouldn't Kazuo Ishiguro's The Remains of the Day be vastly improved by the addition of a fiddle-playing monkey and a small army of ninjas? Of course it would.

I appeal to you folks out there in Internet-Land. What are other Laws of Fiction?

*Edited to fix the spelling of Chekhov's name. Apparently, the more common transliteration schemes spell it with an "h." Whoops. Dang Cyrillic writing system...
