As for Christy’s debut on the show, it did not take place until April 24, 2003, when the The Howard Stern Show would broadcast from the Hard Rock Hotel and Casino in Las Vegas. However, his regular appearance on the show came after winning the “Get John’s Job” contest on July 1, 2004. A year later, Christy landed his own show airing semi-regularly throughout the year. There, he gained popularity for the prank calls, song parodies, personality, and stunts he performed on the ether. While as a stand-up comic and actor, he both appeared and directed several independent films. His voice has also been heard on various animated programs for the Adult Swim programming block, such as Metalocalypse and Rick and Morty, as well as the Cartoon Network series Uncle Grandpa. In 2017, Christy was seen in a cameo appearance in the Marvel film Guardians of the Galaxy Vol. 2, playing the character “Down There.”
