Many believe that foil hats are an essential tool to protect against government oppression via brain wave reading/manipulation.  A study from MIT examines their effectiveness, and shockingly concludes that the foil hat craze may have been *created* by the government in a cunning example of misdirection, and  they may actually increase the ability of the men in black to control the minds of the wearers.  A True Believer©, however, has issued a rebuttal calling the the study into question.
