This was an interesting show. I agree with Penn on most of his stances (except his extreme pro-monopoly attitude), and didn't have much of a problem with listening to this show daily. It was only an hour long, and was certainly a better option than garbage like O&A.
The only time I switch to another station on the dial (or just sit in silence) is when this $#@! is on. He goes on and on about the most inane things, and his badly timed and horrendous laughter doesn't help. I actually like him on the stage when he does his shows with Teller, I just wish he would stop doing his radio show.
Open minded in discussion and very analytical. I have plenty of respect for his opinion, even when I disagree. Best part of the show is Monkey Tuesday.
