This week on Car Talk, DIY filmmaker Seth is preparing to shoot a big scene: a car explosion in the front yard (of his neighbor's house, of course). Seth's hoping Tom and Ray can help minimize the risk of seeing his house go up in smithereens, and his eyebrows getting that old familiar "Acme Dynamite" look. Can our Chief Counsel Hugh Louis Dewey duct tape the guys' mouths before they wade in to litigious waters? Elsewhere, Michael's RAV 4 is whining in the cold weather even louder than Tommy usually does; Ray trips the Bogosity alarm by introducing the "Connecting Rod Stretch Theory" to explain an Explorer's knocking sound; and on Stump the Chumps, did Tom and Ray diagnose the "amorous donkey" noise in Joan's Honda? All this, and lots more, this week on Car Talk.
