I've heard Jim Breuer on other shows though. He's just garbage.
Never listened to O&A. I haven't listened to morning radio shows in quite some time, and even when I did I was sad and ashamed of all the asshats wrapped up in inter-show feuds. It's relatively embarrassing. I was under the impression that most Stern diehards had somewhat turned on him at this point, since he has kinda checked out (4 shows a week, frequent vacations and hiatuses).
