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.

The idea that you can contribute is really important, especially for a kid.

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.

Sometimes the best people to be around are not exactly like you - because if they were, what is the point? If they contribute something different than you can, that is when they are valuable.

We may not have a sample size larger than one, or we may not have unlimited resources - it's a TV show, and we generally turn these things around in about a week or so.

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

Science isn't just for scientists and guys in lab coats. It's something that everybody can do.
