David and I just got off the phone with Matt Stone (coolest sentence I’ve ever written). He was extremely nice and apologetic. He explained that when they couldn’t get a copy of an Inception screener, they used our sketch as source material. They thought that the lines in our sketch were taken directly from Inception (and the joke was that they were arranged in rapid succession), rather than original lines written by us.
It turns out that the South Park/CollegeHumor issue was a mistake by the South Park guys. Here’s Dan Gurewitch, who co-wrote the original CH video:Fair enough! It seems weird that they didn’t get the joke and, even if they saw it as they did, copied it so heavily. But it’s not a big deal, and I’m glad that everything worked out.
