I don't know about dan, but I listen to "Car Talk" every Saturday morning (it's on from 10-11 down here) on the local NPR station. Guys are hilarious; I love the puzzlers. My situation might not be a bad one to call in, but they seem to prefer talking to people whose cars are making funky sounds which they like to make them imitate. I've heard that's the surest way to get past their call screeners.
