It wouldn’t surprise me. From what I’ve seen of the show they seem to be good at pushing the right buttons. Come to think of it, in the intro they show the people hooked up to the polygraph so since they tape the test maybe they use a body language expert to pick some of the questions.
I sent an article to Dave Barry yesterday and he put it on his blog and I got a "Thanks to Beth.." I'm freaking! He's my hero and I'm so excited!!!
