My relationship with my mom is so amazing. We never got to have that stage that people go through like when you're 13 and you think you're too cool for your parents. When you're embarrassed by them and stuff. We never went through that because I was constantly working and she constantly had to be there.
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.
