Me and Mikey Boy Civins are pretty big fans of Tom Scharpling, host of The Best Show on WFMU. Tom is a really funny, nice guy, who essentially pretends to be a bully for three hours, hanging up on callers randomly when he wants (but always in a funny way), being nice to other callers randomly, and always seemingly honest about the music, movies, TV, and comics he likes.
One of the show's best moments came after Tom, who is an avowed Kevin Smith hater (much like myself), saw the god-awful Clerks II and ripped into Smith for about an hour. It's some of the best radio I've ever heard. Check it out here at the Best Show Archives: the July 25, 2006 episode, about 1 hour, 59 minutes in.
