This American Life did an episode about a guy who was a polygraph operator; discovered how flawed it was; and has been crusading against them ever since and teaching people how to beat them. Worth an hour of your day:

Yes. That's the story of our friend, Doug Williams, who was targeted for entrapment by federal agents in a criminal investigation that targeted polygraph countermeasure instructors. We briefly discuss his case in the section on "Operation Lie Busters" in Chapter 4 of The Lie Behind the Lie Detector.
