This week on The Best of Car Talk, Bob is worried his car may have a permanent case of athlete's foot (or worse) after a sock got sucked into the engine. Find out how the sucking transpired and whether Tom and Ray can stop laughing long enough to ease Bob's fears. Elsewhere, Patty's Accord began mooing at her. Is her best option to try milking it? Also, Elizabeth came home from Thanksgiving to discover her Volvo's windows permanently fogged; Marlene got talked into buying an electric anti-rust device for her new car; and Mike may re-think his desire for a "heavy duty" clutch after he hears Tom and Ray's tale of the customer known as Mr. Heavy Duty and his enlarged left foot. All this and more, this week on The Best of Car Talk.
