What is the Secret? I thought I'd bestow curiousity on you, like it did me. What is the Secret? A lame publicity stunt? A serious secret that will change lives? I don't know. I'm going to watch whatever it is. Whatever the Secret is, the website did was it was suppose to do, get you curious. At first I thought it was National Treasure 2 or the Da Vinci Code movie version. But then I realized some things. That it was a T.V. show (not a movie), no one in the right mind would make another National Treasure. and that the Da Vinci Code movie is coming out in May.
