This week on Car Talk, a few choice lines from Rodney Dangerfield set the stage for Sam in Vermont, who's about to learn he has a cracked block--and his car isn't doing so hot, either. Also, a married Dad's need for speed hits a bump in the form of his wife, and Tom and Ray; a Yukon owner tries to convince her Dad and her mechanic that her car really is making a strange noise; and a cardinal becomes overly fond of a Side-view mirror.
