I think your grasping at straws there. I don't listen to many top 40 radio station morning shows, but from what i have listened to its obvious a lot of the more outrageous callers are obviously fake, and these shows can hardly be considered real talk radio. Phil Hendri is the only actual talk radio show host who obviously uses fake callers to incite real people to listen, but I believe most of your more political oriented talk radio shows like Rush Limbaugh, Hannity, Ingram, Levin, and Boortz all take real calls from real listeners with real opinions. Most of them do filter out the boring calls or the ones that they don't feel will grab the listeners attention, but they are real none the less.
