Park, and if we don't do this, we're belittling everything else we've ripped on. Although some questions were raised prior to the episode's screening about whether it was wise to take swipes at Cruise and Scientology, Comedy Central declared that it supported Stone and Parker. A Comedy Central spokesman told Radar magazine in November 2005 that "they are free, and have been, to satirize anybody and anything they want to. They've made fun of MTV, they've made fun of Viacom, they've made fun of Comedy Central, and we've never interfered with them." During production on the episode, investigative journalist Mark Ebner served as a consultant to Stone and Parker. Ebner had previously authored The New York Times best seller Hollywood, Interrupted, which includes an analysis of the Church of Scientology and its effects on the culture in Hollywood, and has a chapter on Cruise and Travolta's relationship to Scientology. On the official Comedy Central website for the South Park episode, it is asserted that the section of "Trapped in the Closet" that explains Scientology's portrayal and beliefs was not exaggerated: "Nothing about what you see here is exaggerated in the slightest. Seriously." The title is a reference to the R. Kelly song and music video series of the same name, and a depiction of R. Kelly appears in the episode to sing a parody of it. Controversy Isaac Hayes' departure On March 13, 2006, a statement credited to Hayes, a Scientologist himself, announced that he was quitting the show because of the series' treatment of religion, saying, "There is a place in this world for satire, but there is a time when satire ends and intolerance and bigotry towards religious beliefs of others begins. Religious beliefs are sacred to people, and at all times should be respected and honored. As a civil rights activist of the past 40 years, I cannot support a show that disrespects those beliefs and practices." The Guardian observed that the show had mocked most other religions, but that he drew the line at Scientology. Later in an interview on CNN's Showbiz Tonight, Hayes added he did not see the episode itself, but was told about it. In a separate interview, he reportedly said regarding Trey Parker and Matt Stone, "Guys, you have it all wrong. We're not like that. I know that's your thing, but get your information correct, because somebody might believe that shit,
