Trey Parker and Matt Stone’s 60 Minutes interview is, in large part, an impressive look back at how often the South Park guys have just killed it, beginning with Cannibal! The Musical in 1993 and ending (so far) with this year’s Book of Mormon. The most awe-inspiring aspect of Parker and Stone’s success, however, would have to be the fact that they’ve sustained a functional 20-year-long creative partnership without some kind of Hollywood-style hotel-room-torching break-up. “At this point, it’s kind of like a marriage,” admits Stone. Says Parker, “It’s funny. We’re just at that level now where it just doesn’t happen anymore where one of us can say to the other, ‘You know one time, I was doing this…’ Because it’s like, ‘Yeah, I know. I was there.’” Book of Mormon producer Scott Ruden explains, “Sometimes I’ve seen people try to triangulate one against the other. You see people try to get between them; they shut it down so fast. They have each other’s backs in the absolute best possible way…They are genuinely a partnership,” all of which makes me believe in the institution of actual marriage just a teeny, tiny bit more.
