I'm surprised that no one has mentioned this before, but there is one thing that I "took away" from Rush's show, years ago. It involves fortune cookies, that you can get at a "Chinese food" restaurant. I call it "The Limbaugh Method of Reading Fortune Cookie Fortune Strips." This was many years ago, but on one show I heard him tell about how you can put a whole, new "twist" on a fortune strip, but adding two simple words, at the end of your strip. And, those two words are: "In bed." That's right, "in bed." Try that some time, next time you get a fortune cookie, and read the strip inside. (Oh, I suppose that you COULD any two words that you want to, such as, "At home", or "at work", or "at school." But, try the other words that I mentioned.)
At any rate, since this OP is about a radio talk-show host who has recently demised, I have a certain book that might be of interest to people out there. Its title is: "Inside Talk Radio: America's Voice Or Just Hot Air?" The book was written by Peter Laufer, who has spent his entire career in radio and TV broadcast journalism, including being, himself, a host of a talk-radio show; so the book was written from the perspective of a radio personality, not an "outsider." I bought it at a nearby discount-price book store 18 years ago. Have fun with the "fortune" cookies.
