I think "MythBusters" is a step up from special effects because we not only have to make things look like they work, they actually do have to work. It's more challenging and even transcendental.

There are a lot of things that I'd do differently. But I can't imagine being more fortunate than I have been.

I have to say for both of us [ with Adam Savage], this experience that we've been having here has changed us dramatically, and we've evolved since we've come on the scene with Mythbusters, because of what we've learned, and that, I think, is the biggest reward for us.

I think LEGOs are one of the best toys ever developed. While LEGOs are sold in kits in order to build specific things, there [are] very few people who leave their LEGOs in those kits. It very rapidly becomes an open system where you can build whatever you want. That's the one thing that signifies my entire life and my career. 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.

If it turns out that we're doing proper science from time to time, it just happens to be that that's the most efficient way of doing it. We go into each of these stories with an open mind, and one of the great things about how the show works is that we're not approaching it from a doctoral point of view, we're just trying to see what happens.
