Stand-ins For Limbaugh
Every so often, Limbaugh is absent from his show, whether for various personal reasons or because of extended trips. For instance, in early 2005, Limbaugh took a week-long trip to Afghanistan to report on postwar conditions; he's also participated in various celebrity pro-am golf events, especially when he represents his parent company, Clear Channel. On those occasions, Limbaugh allows “EIB certified talk show hosts” (sometimes called "Associate Professors from the Limbaugh Institute for Advanced Conservative Studies") to fill in for him. Typically, these hosts are well-known conservatives, and since Clear Channel acquired the network which syndicates the program, they have often been Clear Channel radio hosts.
