Question:
Joe Tex was born Joseph Arrington, Jr. in Rogers, Texas, in Bell County to Joseph Arrington and Cherie Sue (Jackson) Arrington. He and his sister Mary Sue were initially raised by their grandmother, Mary Richardson. After their parents divorced, Cheri Arrington moved to Baytown. Tex played baritone saxophone in the high-school band and sang in a local Pentecostal church choir.
Tex recorded for King Records between 1955 and 1957 with little success. He later claimed he sold musical rights to the composition "Fever" to King Records staff, to get money to pay his rent. The song's credited songwriters, Otis Blackwell (who used the pseudonym John Davenport) and Joe Cooley, disputed Tex's claims. Labelmate Little Willie John had a hit with "Fever", which inspired Tex to write the first of his answer songs, "Pneumonia".  In 1958, he signed with Ace and continued to have relative failures, but he was starting to build a unique stage reputation, opening for artists such as Jackie Wilson, James Brown, and Little Richard. He perfected the microphone tricks and dance moves that defined the rest of his career. Many, including Little Richard, claim that Tex's future nemesis James Brown stole Tex's dance moves and microphone tricks. In 1960, he left Ace and briefly recorded for Detroit's Anna Records label, where he scored a Bubbling Under Billboard hit with his cover version of Etta James' "All I Could Do Was Cry". By then, Tex's use of rapping over his music was starting to become commonplace.  In 1961, he recorded his composition "Baby You're Right" for Anna. Later that year, James Brown recorded a cover version, though with different lyrics and a different musical composition, gaining songwriting credit, making it a hit in 1962, and reaching number two on the R&B chart. During this time, Tex first began working with Buddy Killen, who formed the Dial Records label behind Tex. After a number of songs failed to chart, Killen decided to have Atlantic Records distribute his recordings with Dial in 1964. By the time he signed with Atlantic, Tex had recorded 30 songs, all of which had failed to make an impact on the charts.

Answer the question at the end by quoting:

"Trapped in the Closet" is the twelfth episode in the ninth season of the American animated television series South Park. The 137th episode of the series overall, it originally aired on Comedy Central in the United States on November 16, 2005. In the episode, Stan joins Scientology in an attempt to find something "fun and free". After the discovery of his surprisingly high "thetan levels", he is recognized as the reincarnation of L. Ron Hubbard, the founder of the church.
Saving for a bicycle and not wanting to spend money on entertainment, Stan takes a free "personality test" being offered by Scientologists on the street. After answering a long questionnaire, Stan is informed that he is extremely depressed and therefore a perfect candidate for Scientology. They offer to help him out for $240. Back home, Stan asks his parents for the money. His father suggests that he use the money he had been saving. Stan pays and is taken into an auditing room where an attendant reads his "thetan levels" using an "E-meter". Stan has such a high reading that the Scientology headquarters in Los Angeles is notified. There, the president of Scientology determines that, because his reading is so high, Stan must be a reincarnation of L. Ron Hubbard, Scientology's founder and prophet.  Later that night, a large group of Scientologists, including John Travolta, gather outside the Marsh house to celebrate Hubbard's "second coming". The president of Scientology arrives in a helicopter and talks with Stan's parents. They are opposed to Stan's participation, but the president informs them that "we're not asking him to join us; we're asking him to lead us". Randy sends Stan to his room, where he finds Tom Cruise waiting. Cruise, believing that Stan is genuinely Hubbard's reincarnation, asks him whether he has enjoyed his acting. When "Hubbard" replies that his acting is okay but not as good as others' such as Leonardo DiCaprio or the Napoleon Dynamite guy, Tom hears that he is "a failure in the eyes of the prophet" and locks himself in Stan's closet. He refuses to come out, despite the entreaties of Randy, Nicole Kidman, the police, Travolta and R. Kelly to "come out of the closet". Travolta and Kelly eventually join Cruise in the closet.  Downstairs, the church president tries to convince Stan's parents to allow their son to participate. He tells to Stan the great secret behind the church -- a condensed version of the story of Xenu, based directly on the Scientology Operating Thetan III document, and accompanied by an onscreen caption reading "This is what Scientologists actually believe". He then begs Stan to continue writing where "L. Ron" left off. Stan, impressed by the story, does so. He shows his writings to the Scientology president, who initially approves of the work, but when Stan says "to really be a church, you can't charge money to help", the president reveals to Stan that the church is in reality a global money-making scam. He asks that Stan continue with that in mind. Stan appears to agree and keeps writing.  Outside the house, the president introduces Stan to his followers, to whom he will read parts of his new doctrine. However, instead of presenting it to them, Stan states that he is not the reincarnation of L. Ron Hubbard, and that "Scientology is just a big fat global scam". The Scientologists grow angry and threaten to sue him. The celebrities in the closet appear, threatening to sue Stan as well. The last shot is Stan daring them to do so. However, that shot is followed immediately by the closing credits naming only "John Smith" and "Jane Smith", a reference to Tom Cruise and the Church of Scientology's reputation for litigiousness.
