Stone is also involved in the animation and writing. He contributes more than you realize.

I would definitely want to have a conversation with both of these guys.

What if its exactly like 'FISHSTICKS'?
Seriously though, I'd wager that @ some point 1 of them was SOL & had only the other & now they remember each other since their back on top!
I fell asleep during INCEPTION BUT I FEEL like I still saw it!

Are you a cartoonist? Matt Stone has talent in the arts. Didn't you know this? Lol.
Anyway, I think I'll blame Parker here for being the "dominant" one. He's probably overbearing and territorial. He voices likes 90% of the characters on the show, and does most of the other work. He probably likes to do things his own way, and is resistant to change or advice.
I really need to hear more of Stone's voice personally.
Fashion is a form of ugliness so intolerable that we have to alter it every six months.

Well if you were his friend, you'd best be careful what jokes you make around him, because he'll put them in the show and take all the credit for himself.

I didn't see the point of Matt Stone until he started playing 'Butters'!

I sometimes wish I knew Matt and Trey personally.
Lars Ulrich is a Brony

Matt is more Trey's assistant.
He does the businessy side of South Park. Like handling the money because Matt is Jewish.
