Assuming that you believe the source: no, not Cracked.com. Those guys are pretty reliable, for given values of ‘reliable.’ But they got this one off of a Commondreams reprint of a Guardian article, so you have to wonder how much is true, and how much is ‘betcha I can make ’em believe it.’
I should also note that the likelihood of it not working is perhaps lower than people might think; the arguments for it are persuasive.
