'South Park' Sued for Supposed Copying of YouTube Video

South Park producers, Viacom, and Comedy Central are under fire again, as they are being sued for supposed copyright infringement. According to The Huffington Post, the show is alleged to have copied the song "What What (In The Butt)," which appeared in a 2008 episode. It was originally performed by Sam Norman, produced by Brownmark Films, and posted on YouTube.

According to The Hollywood Reporter, "Brownmark Films filed a copyright infringement lawsuit in U.S. District Court in Wisconsin [on Friday], alleging that the infringement is 'willful, intentional, and purposeful in disregard of and indifferent to the rights of Brownmark.'"

This is the second time this year Viacom will be present in court. In June, the company lost what was considered to be a "landmark copyright case." The cable network attempted to get $1 billion from YouTube for copyright abuses, but the judge ruled in favor of YouTube before the case went to court.

Also, creators of South Park were under fire after airing their parody of the movie Inception, when they used dialogue from another parody of the movie made by CollegeHumor.com.

Comedy Central issued a statement to The Huffington Post, saying that they believe their video is fully protected under the First Amendment law, which protects the use of copyrighted work if the intent is satirical.

They also said they planned to "vigorously defend those rights."
