This week on Car Talk, Susan leads a double life--Philosophy Professor by day, and animal rescuer by night. Unfortunately, she's come to realize her beloved Honda Civic can't handle the olfactory implications of her full range of clientele. Can Tom and Ray help her find the perfect Pig and Prof-mobile? Elsewhere, Jim's having dipstick removal issues; Dave's wife's friendliness is scaring the dickens out of him; and Samantha and her husband are having a raging debate over… how best to hang dry cleaning in a car?  Really? And, on Stump the Chumps, we find out if the second carburetor was the charm for Chelsea. All this, plus an explosive tale from Ray's high school days, and lots more, this week on Car Talk.
