South Park creators Matt Stone and Trey Parker are not only admitting to copying the Inception parody from the College Humor website, but they're also apologizing for it.
Co-creator Matt said that they had a short turnaround and they were unable to find a copy of the movie before the episode's deadline. He added:
"It’s just because we do the show in six days, and we’re stupid and we just threw it together. But in the end, there are some lines that we had to call and apologize for. We thought their joke was that a lot of those lines were actually in the movie and they were banging them against each other, and showing that the Inception characters didn’t even know Inception. That was a mistake, and it was an honest mistake."
At least they're owning up to it. Who cares, right?? It was still a funny episode.
