This week on Car Talk, Karmen's husband is a "burper." At the gas pump, he shakes the car to get the air out, and more gas in. Karmen thinks this is wacko--which it is--but is her nozzle technique any less crazy? Elsewhere in matters auto-relational, Jim just noticed that all of his romances have been with women who drive Volkswagens; and Derek needs to get his beloved Jeep off the front lawn, before his wife gets him out of the house. Also, a passenger-side farting sound is causing some major embarrassment for Alicia; Paul needs to figure out why his wife's Hyundai is moaning before she gives birth; and Ben is wondering if a potato can really fill in for a radio antenna. All that and lots more, this week, on Car Talk.
