My first serious girlfriend, when I was 16, was Mormon. I went to her house for 'family home evening,' and I was like, 'Why aren't you people ignoring each other and watching television?'

Hippies, hippies... they want to save the world but all they do is smoke pot and play frisbee!

You don't need missionaries in Colorado; you got Colorado.

Well I looked in my moms closet and saw what I was getting for Christmas, an ultravibe pleasure 2000.

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

So we're considering doing a new Christmas album, because there's been Christmas episodes since then, and maybe finally do the version of 'The Most Offensive Song Ever' with lyrics intact.

It's not like we have a formula, but I think one of the reasons this show has survived is that it has a big heart at its center. Other cartoon shows have people crap on each other and make racist jokes. But I don't think people tune in for that. I just don't think a show lasts for 10 years without a heart.
