Uncle Sam wants--Tommy? Yes, it's true: the elder Magliozzi was once a member of the U.S. Army, and, as with most of his relationships, it didn't end very well. This week on Car Talk, Tommy tells the tale of those precious few hours during which he actually rose to the rank of Private-- and what caused Sergeant McNeeley to almost immediately rip that stripe off his shoulder. Also from the Tommy files, some sure-fire ways to alienate your co-workers, and maybe get a little cash at the same time. Meanwhile on the automotive front, take a 3-year old, give him a golf ball, put a Saab exhaust pipe within reach, and voila--you've got a Titleist nesting in your muffler. Plus, why a Volvo owner may wish she'd married a gecko, and can a folk singer keep an oily promise on her cross-country tour? All this, plus lots more on this week's encore edition of Car Talk.
