How can you contact Trey Parker and Matt Stone?
Below in the related links is a Trey Parker fanclub they have contact information there for both Trey and Matt. I would try that address!
There are two creators, Matt stone and trey Parker. Trey writes most of the episodes and does a few more character voices than Matt,he has the dirty mind and comes up with the stupid things that make everyone laugh and he works hard doing it, if it werent for him south park wouldn't be as crazy as it is, so i would say trey Parker.
