The creators of 'South Park,' the animated Comedy Central series, apologized Friday to the creators of a Web comedy video satirizing the summer blockbuster 'Inception,' saying they had used dialogue from a video on the website CollegeHumor.com. 'It's just because we do the show in six days, and we're stupid and we just threw it together,' Matt Stone, who created 'South Park' with Trey Parker, said Friday in a telephone interview. 'But in the end, there are some lines that we had to call and apologize for.' The Web video called 'Inception Characters Don't Understand Inception,' was written by Dan Gurewitch and David Young, and posted on CollegeHumor on Aug. 2. It is loosely modeled on a scene in 'Inception' in which a team of characters is trying to transport a wounded colleague. The 'South Park' episode shown Wednesday had a similar scene that contained dialogue often similar to or identical to the CollegeHumor skit. In the earlier skit a character says, 'We need to move to the next dream level before these projections kill us'; on 'South Park,' a character says, 'We need to move them all to the next dream level before the projections kill them.' In both skits, a character says, 'Sometimes my thoughts of my dead wife manifest themselves as trains.' Stone said he and Parker wanted their 'South Park' episode to satirize the verbal complexity of 'Inception.' 'It was like, 'Let's parody the gobbledygook' -- because honestly, that movie -- all those explanations, and explanations of explanations,' Stone said. When Parker and Stone could not find a movie theater showing 'Inception,' and were unable to get a DVD of the film (or find a watchable version on BitTorrent), they turned to other parodies of the film on the Web, and found the CollegeHumor video. 'We thought their joke was that a lot of those lines were actually in the movie,' Stone said, '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.' Gurewitch wrote on his personal blog that he and Young accepted the apology of the 'South Park' creators. 'All is well,' Gurewitch wrote, 'and we're going to meet up with Matt and Trey when they're in New York.'
