Hey SpiritFox, be jealous. I have the complete first season (I believe it was for XMas last year) as well as a book that gives a short bio on Jamie and Adam and goes through 30 of the myths they tested on the shows. It was published in 2005 and has a list of 12 myths that they stated were probably never going to be tested on the show. Interestingly, four of them have since been tested.
I have to say that the concrete trucks have to be one of my favorite myths. Jawbreakers are up there as well and anytime I get to hear Adam do his impression of Jamie.
