On a side note, this list made me recall Dan Savage's old KCMU call-in show back in the early 90's. It wasn't a comedy show, but often very funny.
I have two memories of that show:
1) the bestiality guy from from the midwest, who argued with Dan for 20 minutes. Dan asked him if his horse was male or female, and the guy got mad -- "I'm not GAY!!!"
2) Rocket ... ... ... ... Pizza.
True story: everybody who worked on Dan's show hated him but they were all afraid of him. When the building where they recorded the show was torn down they didn't tell him. He just showed up one day and there was no studio. That was how the show ended.
