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.

We have it, we're lucky enough that we've created a show where it's not about... a family, or a kid, it's about a town.

I spend shockingly little time thinking about real-world stuff.

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.

What we're always looking for is weird social issues and weird connections to make. Luckily for them, there's no shortage of material.

I would let my kids watch this stuff way before I'd let them watch something like 'Full House' that I think would make them stupid.

We're the guys who, if someone says you really shouldn't do an episode making fun of Scientologists, we say, 'Whatever.' Someone says, 'They might come try to burn your house down,' we say, 'We'll just get another one.'

In terms of the creative side of it, it's really been a thing where you come up with the funny stuff is usually at a bar or out talking to people or whatever.

Sometimes what's right isn't as important as what's profitable.

Saying goodbye doesn't mean anything. It's the time we spent together that matters, not how we left it.

Me and Matt love to argue, but in general our sense of humor is pretty much alike.

Jerry Bruckheimer creates comedy, he just doesn't realize because he's a turd.

It's funny because I think a lot of it is simply... We've never considered ourselves satirists, but because we're on Comedy Central and because we're South Park on Comedy Central, we can do any topic we want.

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.

We find just as many things to rip on the left as we do on the right. People on the far-left and the far-right are the same exact person to us.

We made this really dumb decision to put on the cover nothing from South Park but just a real life photo of a piece of pooh dressed up like Mr. Hankey, and a lot of people didn't, they didn't even know what it was.

Sean Penn's really the only one stupid enough to put anything down on paper.

We created a brand for ourselves, so that now people can't get mad at what we do, because then they're just making of themselves.

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.'

Careful?! Was my mother careful when she stabbed me in the heart with a coat hanger while I was still in womb?

No, writing musicals is the hardest thing in the world. And it was really funny, because I remember when the South Park movie came out, there were some critics that said, 'Well it's obvious that in order to get it to be 90 minutes they filled some time with music.'

The problem is we moved to LA... The only way to be punk rock in L.A. is to be a Republican.

Hollywood views regular people as children, and they think they're the smart ones who need to tell the idiots out there how to be.

I almost bumped into Alec Baldwin and then turned around and Paris Hilton was standing there. And I was like, 'Look, it's stupid spoiled whore.'

You know, and it really doesn't have a lot to do with the movie. That's the trick to doing a good musical is that, if you take that music number out, there's less to the movie there. You would miss it.

You know that everyone thinks that in order to do South Park we must be wild, crazy, rock and roll stars. But the truth is we're just wholesome middle-American guys. We enjoy soda pop, baseball and beating up old people just as much as anybody.

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.

I would never kill somebody, unless they pissed me off.

There is nothing we can't do. So it's just the fact that we're doing topics like that that other people, especially network TV, won't touch, that we're satirists.

It's this simple law, which every writer knows, of taking two opposites and putting them in a room together. I love anything with Cartman and Butters at the same time, it's great.

It was exactly the same on the South Park movie really too. There's lots of violence in that too, but it always came down to anything sexual... They don't care about anything else.

My favorite musical? I don't. It changes all the time. I'm just a diehard, I'm totally old school, like I'll sit and watch, if they are re-doing Oklahoma in New York, I will be the first one there.

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.

All the religions are super funny to me.

Any job is a job. If you have to be doing something, then you're probably not enjoying it.

Bargaining makes you come up with the best ideas.

Colorado's right next to Utah - you know, Mormon Central.

Doing a musical is like having a kid. It's out there alive somewhere. It's not like a movie or a TV show where what we intended is what everyone will see. The kid can act out. The kid's going to do what it wants to do.

Even from the very beginning, I didn't put any money in the stock market.

Even if you're not Christian, just from being in our culture you know Jesus and resurrection and redemption.

How many times have you been watching an episode of 'South Park' and thought, 'I'd like to be able to watch this on my television while hooked into my mobile device, which is being controlled by my tablet device which is hooked into my oven, all while sitting in the refrigerator?'

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

I can feel myself dying inside.

I don't even know where Russia and Mexico are.

I don't want to say never, but I hope I don't become that 'take me seriously now' guy.

I find Mormons adorable.

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.

I grew up with the religion of 'Star Wars,' frankly. That's when I realized there is something bigger out there... and it's called The Force.

I hate puppets so much.
