I just had one of those 'what the hell are we doing' moments.

I learned at an early age that I could make the things that I wanted. That's a very powerful thing to realize as a kid. LEGOs were a key part of that.

These are people from everywhere, from Lawrence Livermore and JPL and Sandia National Labs, the FBI, all over the place, real scientists who see what we're doing, and they consistently thank us. "I agree your results aren't always right," they'll say, "but your methods are clearly showing that science is a re-creative process, and it's an interesting process because it's messy, and no other shows show that."

The difference between screwing around and science is writing it down.

Of course, I love tools. I also love arranging them, to the point where I came up with a name for my organizing metric: first-order retrievability.

The 'Mythbusters' crew, we monitor the Discovery boards, we look for the new ideas that are being forwarded on those boards, and we keep track of what's going on, we keep updated.

The explosions, like the urban legends, are a great way of bringing people in to watch, because it's really fun, and you know we're always going to give you a satisfying ending.
