Rush did used to have a TV show, and I remember watching one episode some point in 1993, and Limbaugh's mannerisms as far as the show were very Jon Stewart-ish as far as he was more satirizing than he was a person that kept on screaming at liberals. One show I remember of Limbaugh in a small screen reacting to a protester getting up at an event Clinton was at and detailing his list of complaints about Clinton. Clinton then talks about how the protester had the right to do this and he was right to say those things, which Limbaugh in a Jon Stewart fashion oversells with his facial reactions, drawing laughs.
