I think of my films as not necessarily political but more moral. Between my father, my stepfather, and my mother - they all felt pretty passionately about the importance of standing up and doing the right thing, and none of them were suck-ups. What motivates me is usually abuse of power.
I did go on safari in Kenya when I was 17, with my mother, stepfather and little brother, and I kept a careful journal of the experience that was very helpful in terms of my sensory impressions of Africa. I have traveled quite a bit at distinct times in my life, though now that I have kids I've settled down.
A lot of people don't realize this, but probably the one person that gets made fun of in 'South Park' more than anybody is my dad. Stan's father, Randy - my dad's name is Randy - that's my drawing of my dad; that's me doing my dad's voice. That is just my dad. Even Stan's last name, Marsh, was my dad's stepfather's name.
I grew up without a father, who was kept a mystery to me. There was a sense of uprootedness, things being one day here and the next day not; a sense anything could happen. Then, all of a sudden, my mother met my stepfather, and her life became happier, and my life changed, my name changed.
I never had that wicked stepmother or evil stepfather thing at all. I'm very close to both step-parents and I consider them to be my parents, too.
