And while we here, on-this-thread, can see the sillyness of it, yet to the average couch potato, they don't see it. The "what if" lure of treasure psychology takes over.
One of my hunting partners and I were discussing the show one day, and ... I would have JUST ASSUMED he'd be on-the-side of skepticism (since he's a very logical fellow). I was surprised when he actually gave credence to it. Citing "unexplained this and that", blah blah.

I was shocked, because this was a guy who I would have thought would have been on the side of skepticism.
So it went to remind me : Yes, it's just human nature. Even to very smart people.
