Tell Me Something I Don’t Know: A New Freakonomics Radio Podcast

A few years ago, I developed a habit. If the person sitting next to me on an airplane seemed like they wanted to have a conversation, I'd ask them a bit about themselves -- let's say they worked in civil engineering -- and I'd say "Tell me something I don't know about civil engineering." The habit became an addiction. I loved learning stuff I didn't know, and most people loved to talk about their passions, work-related or otherwise.

Soon this addiction fueled a dream: I imagined turning it into some kind of a live game show/talk show. It would be called "Tell Me Something I Don't Know." There'd be a host (me), some smart judges, and we'd invite the audience members to come onstage and tell us something we didn't know. We'd learn a bit, laugh a lot, and take advantage of all the amazing information that's floating around in the world.

It took a while to make this dream happen but finally it did, a few weeks, ago, at WNYC's Greene Space.
