This week on Car Talk, the best defense is--a boooogus scientific explanation? Hey, it's always worked for Tom and Ray! Katie's roommate cited the Bernoulli Effect to explain why he gunned the engine to dislodge her stuck car door. She told him where he could stick his Bernoulli. Will Tom and Ray back her up? Elsewhere, Ray has a perfect diagnosis for Heidi's noisy 4Runner--if he can convince her that a "shugga shugga" is actually a groan, and Frank may need a box of doughnuts to help him fix his Forester's creaky window himself. Also, on Stump the Chumps, we find out if Steve's cross-country bachelor party road trip in a '66 Econoline ended with him taking his vows on a tow truck; and, the most perplexing question of the week: Why on earth would anyone steal the seats out of a 1999 Miata? All this and lots more, this week on Car Talk.
