Kerry Jackson grew up in Salem, Utah. He currently lives in Salt Lake City, Utah with his Korean-American wife, Sue. Jackson often references and discusses his love for geek culture including video games, comic books (Marvel Comics, not DC Comics), and science-fiction movies and television series such as Star Trek and Star Wars. One of his favorite video games is the Lego Star WArs series. His large toy collection consists of Batman, Star Trek, Star Wars, and Marvel Comics Action Figures . Kerry regularly plays audio clips from The Cartoon Network's Adult Swim lineup including Aqua Teen Hunger Force, Space Ghost Coast to Coast, Sealad 2021, and Squidbillies.

Jackson often recounts his adventurous weekend experiences (usually involving his fondness for mixed drinks), offers humorous pickup lines, and occasionally performs impressions of celebrities includingLarry Flynt, Roy Horn, Lou Ferringo, and Owen Wilson. Kerry has claimed that he has an innate talent for recreating the voices of handicapped celebrities. Kerry also created the character, "Frank Chryst," a celebrity-reporter who is perpetually grieving over the "horrible, terrible tragedy" of a recently publicized celebrity death.

Jackson also has been candid and jocular about his suffering from possibly a combination of personality disorders, such as Obsessive-Compulsice Disorder, Depression, and Social Anxiety. He says he lies in bed and hears songs or phrases repeat themselves over and over. Mostly these intrusive and repetitive thoughts are Warner Bros. themed. Also, in early 2007, Bill was allowed to read an email from a listener that had seen Jackson shopping, who was noticeably irate and wrathful, due to being surrounded by too many people.

Jackson had a bit part in the film The Singles Ward , but has disavowed his role in the film because he felt it was simply not funny. Despite his best efforts, however, he has been offered a part in a proposed sequel.

Jackson is also responsible for recording, selecting and playing the majority of the sound clips on the show; Allred has described Jackson as the Don Letts of Radio From Hell (referencing Lett's role in rock group Big Audio Dynamite).

Kerry attempted to participate in The World Series of Pop Culture. After traveling to California, his team, "Shatner's Midnight Runners" passed the written exam and were allowed to audition for the producers. The were ultimately cut from the contest and sent home with a calendar for their trouble.
