That's a pretty fun surprise.
Carolla's humor is certainly an acquired taste. When he got rid of Donny, I lost interest in the podcast. The guests just seemed to dry up and the same stale line-up kept reappearing, show after show.
His CarCast, on the other hand, is worth a listen. Great string of guests and fantastic stories, with only a little bit of Carolla humor. For those that like To Catch a Contractor, he has an Ace on the House podcast where he talks about construction and home improvement.
