Guests who go for a Lie Detector test on JK believe that it works

And they are f-cking morons and stupid, because a lie detector test is nowhere near as accurate as a DNA test, and the guests who appear on the Jeremy Kyle Show who have a lie detector test done on themselves, believe that it does work, and they never, EVER question the accuracy of the test when it turns against them. What's more, JK himself humours these guests by saying at that moment, "so the test's wrong?" OF COURSE IT'S WRONG, you DOLT!

Unless of course, JK actually genuinely believes in the LD test? But I think it's more likely he's humouring stupid people on national TV and making masses of money for a dodgy part of science.

Why are you here if you haven't seen the movie yet?
