I wonder if this guy, when seeing Penn & Teller demonstrate how a trick is done, believes it’s some type of do-it-yourself lesson in the occult?
Of course if you try to do stuff the way P&T say you’ll fail and often get hurt. That’s the “hidden” joke of P&T when they show you how to do the trick they’re actually doing a whole other trick, the trick of making it look like that’s how you do the trick. Sometimes they play it square, but most of the time there’s a couple of extra slights they don’t show to make it “work”.
