These episodes run 30 minutes each, and counting 69 through 6 seasons. A mixed-and-cut, 10 minute version of the episode on the Bible is available on YouTube:
I can’t say that I really loved the series. I found them a little bit boring – I rented two DVDs from Netflix and by the end of the first one I’d had enough. There’s too much comedy in it for me, and too little facts.
But there’s something about magicians (which is what Penn & Teller started as, at least partially) becoming debunkers. The one that stands out of them all is, of course, the great James Randi, the man who I passionately admire, who used to put up his own money against paranormal claims. Randi deserves a separate post (and not one!), but amongst other famous magician debunkers I can list Harri Houdini and Joe Nickell.
I think the reason is simple. Magicians deceive the public while the public is aware it’s being deceived, and that’s what makes the experience so astounding. Psychics, fortune tellers and other charlatans use pretty much the same tricks and techniques, but mislead the public into believing they’re genuine. That outrages fair magicians as they often do the job much better but yet never claim paranormal abilities.
(to be objective, I must add that not all psychics are charlatans – a good chunk are delusional, true believers in their own “powers”, even after it’s been demonstrated in controlled experiments they don’t possess any)
