I started listening to his show to mock him but what I've found is a solid host. However, I DO get a good laugh when he has trouble figuring out his boards.
Same here. It doesn't matter so much if you mumble, really. He might be garbled at times, but his voice is also rather calm and soothing for falling asleep to. He has good guests. He has only had one show I couldn't listen to the entire show, don't even remember why. Also, he doesn't interrupt his guests, and he tries not to put importance on whether you believe in what the guest is discussing or not.
