Know Any Good VRBs?

Help! I need a new podcast to listen to. My Virtual Running Buddies (VRBs), Megan Morrone and Leo Laporte will no longer be running with me by the end of next week (by this time I will have caught up on all past episodes). Due to lack of time to devote to the show, Megan has decided to cancel it. Now I am searching for a new podcast to listen to while I run. Any suggestions would be greatly appreciated. Any other run time entertainment ideas? (I don't have a space in the area for a TV so that is out.)
