One of my favorite comedians has a radio show! Listen here (commercial free!) after the show is over if you can't hear him on the radio. Talk radio seems like a difficult venue (I typically run out of things to soliloquize in about 5 minutes). It takes practice, and they usually get better over time. But listening to his first show, I'm already impressed.
When informed that they didn't have the audio from surrender-monkey Murtha, he said, "Jack Murtha makes so little sense that his voice won't commit to audio tape."
