With this episode, we're having a bit of fun. You're about to hear a great episode of a TED Audio Collective podcast ... but, we can't tell you which one.

Though we can promise what you'll hear will be true to TED: a curated podcast for the curious, whether it's about business, design, science or philosophy. If you can handle the mystery, stick around -- and dive into our entire portfolio at audiocollective.ted.com.
