The creators of “South Park,” the animated Comedy Central series, apologized on Friday to the creators of a Web comedy video satirizing the summer blockbuster “Inception,” saying that they had used dialogue from a video on the Web site 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 on Wednesday had a similar scene that contained dialogue often similar to or identical to the CollegeHumor skit.
