Christy became an avid listener of The Howard Stern Show in 1996 when he moved to Florida, listening to the program "every morning religiously" with headphones while he worked as an electrician. After he obtained the number to reach the show's answering machine from the Internet, he began to submit comical voicemail messages in 1999, that were played frequently on the air. From 2001, Christy began to send in song parodies and bits about staffers Robin Quivers and K.C. Armstrong. His made his debut appearance on April 24, 2003 when the show was broadcast from the Hard Rock Hotel and Casino in Las Vegas. Christy lost a round of blackjack in hope of winning a date with a porn star.  Following the departure of "Stuttering John" Melendez in February 2004, Stern announced the Get John's Job contest a month later, pitting ten listeners who had contributed to the show against each other in competition for the vacated position. Each contestant was given a week to display their talents they could bring to the show, after which the listeners voted online for their favorite. Christy produced a required demo CD of his bits, and was selected to compete for the prize of an initial three-month contract and $25,000. Leaving Iced Earth was a difficult decision for Christy, but felt he could not waste the opportunity to pursue his "dream job" and work for Stern. He had also grown tired of living in Florida, and wished to move. On July 1, 2004 Christy won the contest with 30% of the vote; Sal Governale was second with 24%. By September 2004, both had joined the show as full-time staff members. Christy then relocated from Florida to New York City, where the show is based.  Christy has become known on the show for his prank calls, song parodies, and outrageous stunts, usually performed with Governale. He faced challengers in porn trivia in Stump the Perv, vomited on guests, received a bikini wax, and painted his genitals. From 2005, Christy performed nationwide as a stand-up comedian as part of the Killers of Comedy Tour with other show cast members.  In 2006, the show relocated to Sirius XM Radio. Christy hosted his a semi-regular metal show on the Liquid Metal channel named Richard Christy's Heavy Metal Hoedown. Christy also hosted Inside the Porn Actors Studio on Howard 101, an interview series that parodied the television series Inside the Actors Studio with porn actresses, with Christy filling the role of host James Lipton.
