Stones Law

Named after OliverStone?, director of such acclaimed films as Platoon and Wall Street (not to mention utter rubbish like U-Turn and Natural Born Killers--YourMileageMayVary). Deals with conspiracy theories (see GrandConspiracy).

The law states:

Any evidence which opposes (or tends to oppose) a conspiracy theory was in fact fabricated by the conspirators, and shows just how pernicious the conspiracy really is.

The above may seem silly, until you get into an argument with a conspiracy theorist who attempts to use it against you. At which point you should realize that you're more likely to convince a chair of anything than your opponent.
