The Best Thing About the Freakonomics Podcast?

I was talking to an economics Ph.D. student the other day. Presumably hoping to generate some goodwill, he told me how much he enjoys the Freakonomics podcasts.
I asked him what he liked best about them. He gave an answer that I never would have guessed, and that would likely only come from a Ph.D. type.
He said that he listens to podcasts on his iPod. The iPod only has three speed settings: slower, normal, and faster. Most podcasts, he told me, are hard to follow on the “faster” setting, but something about Dubner’s voice and cadence make him completely understandable at high speed.
Thus, he explained to me, the best thing about the Freakonomics podcast is that he can get through it in almost no time at all.
