In this week’s show, a talk show host’s worst nightmare runs up his pant leg. Could Deborah’s husband be the all-time biggest cheapskate ever to call Car Talk? In a new Stump the Chumps, find out if Tom and Ray gave Hoppy better advice than a bevy of Alaskan drunks. Also, Mary’s steering wheel quacks. Yeah, like a duck. And as if that isn’t weird enough, Laura thinks the Three Stooges are living under her truck. All that, and a few more-plausible calls, in this week’s hour of Car Talk.
