Hoopers! Hoopers! Hoopers!

As CEO of Microsoft, Steve Ballmer was famous for over-the-top enthusiasm. Now he’s brought that same passion to the N.B.A. — and to a pet project called USAFacts, which performs a sort of fiscal colonoscopy on the American government.

The Taboo Trifecta

Serial entrepreneur Miki Agrawal loves to talk about the bodily functions that make most people flinch. That’s why she’s building a business around the three P’s: periods, pee, and poop.

Confessions of a Pothole Politician

Eric Garcetti, the mayor of Los Angeles, has big ambitions but knows he must first master the small stuff. He’s also a polymath who relies heavily on data and new technologies. Could this be what modern politics is supposed to look like?

How to Be Tim Ferriss

Our Self-Improvement Month concludes with a man whose entire life and career are one big pile of self-improvement. Nutrition? Check. Bizarre physical activities? Check. Working less and earning more? Check. Tim Ferriss, creator of the Four-Hour universe, may at first glance look like a charlatan, but it seems more likely that he’s a wizard -- and the kind of self-improvement ally we all want on our side.

The Harvard President Will See You Now: A New Freakonomics Radio Episode

Aziz Ansari Needs Another Toothbrush

Our latest Freakonomics Radio episode is  "Aziz Ansari Needs Another Toothbrush," in which the comedian, actor -- and now, author -- answers our FREAK-quently Asked Questions. (You can subscribe to the podcast at iTunes or elsewhere, get the RSS feed, or listen via the media player above. You can also read the transcript, which includes credits for the music you’ll hear in the episode.)

Aziz Ansari is best known for playing Tom Haverford on Parks and Recreation, the NBC sitcom starring Amy Poehler. The show was never a huge hit, but it was beloved -- In part because it was smart but also because (IMHO) the show was, at its core, sweet. Although Ansari's Haverford was perhaps the most selfish and hustle-y character on the show – and yet he too was pretty sweet, deep down.

Someone Else’s Acid Trip: A New Freakonomics Radio Podcast

At first glance, Kevin Kelly is a contradiction: a self-described old hippie and onetime editor of hippiedom’s do-it-yourself bible, The Whole Earth Catalog, who went on to co-found Wired magazine, a beacon of the digital age.

In our latest edition of FREAK-quently Asked Questions, Kelly sits down with Stephen Dubner to explain himself; the episode is called "Someone Else's Acid Trip." (You can subscribe to the podcast at iTunes, get the RSS feed, or listen via the media player above. You can also read the transcript, which includes credits for the music you’ll hear in the episode.)

Kelly argues that there is in fact little contradiction between his past and present.

The Man Who Would Be Everything: A New Freakonomics Radio Podcast

What is Boris Johnson?

A better question might be: what isn't Boris Johnson? He is, inter alia, the Mayor of London; a prolific author, journalist and, as of this month, a biographer of Winston Churchill; a once and possibly future Member of Parliament; a potential future Prime Minister himself despite being a "self-styled joke" who occasionally gets stuck on a zip-line; an American by birth (and U.S. passport holder).

He is also, as you'll hear in our latest Freakonomics Radio podcast, a painter of old cheese boxes, a collector of wooden tennis rackets, and a man who would inspire England's national soccer team by copying how Saddam Hussein's son Uday reportedly inspired the Iraqi national team: "When they come back next time, we should just, you know, threaten to do something in the changing rooms of those guys unless they sharpen up."

You can also read the transcript, which includes credits for the music you’ll hear in the episode.)

Here's how the Think Like a Freak Book Club works: readers and listeners send in their questions about specific chapters of the book, and Stephen Dubner and Steve Levitt answer them on the podcast. This episode covers chapters 1-3: “What Does It Mean to Think Like a Freak?"; “The Three Hardest Words in the English Language”; "What's Your Problem?" You all sent in some really great questions. Among the ones that Dubner and Levitt take on in the podcast:
