It's been a fascinating thing because we didn't really know how to write when we started South Park at all. It's been like, we've just sort of grown up a bit and it's amazing to just see how, if you take Butters and Cartman and put them in any scene, it works.

I got into this little habit of architecture and building. I designed a house in Colorado and one in Hawaii. The idea is supposed to be build and sell - but then I can never bring myself to sell them.

If we have a great idea, we'll go, 'Oh, this could be a cool movie.' Or really for us, it's more like, 'Oh, this is a really bad idea. Let's do this. This seems really stupid.'

My dad was just a big Joseph Campbell nut.

I bought a house for my mom, I bought a house for my dad, I bought a house for my sister.
