Garrison Keillor: prototypical gaseous windbag.
I heard Keillor exactly one time on an NPR program while driving. He was giving one of his so-called local color stories and obvoiusly thought it was humorous, but I didn't find it the least bit funny or appealing, so I never listened to him again. There was something about the fact that he could even think that hundreds of thousands of people could find it funny which turned me off.
