In this special call-in episode: why some Peruvians eat cats; why operas need repetiteurs; and why we should get rid of prisons. Michael Smerconish (CNN) is co-host; AJ Jacobs (It’s All Relative) checks the facts.

Extra 7: Corrosive Energy Drinks and Peruvian Cat Stew

Journalism wrapped in a game-show package. Host Stephen J. Dubner (of “Freakonomics Radio”) and a celebrity co-host invite guests on stage in front of a live audience to tell us something we don’t know. The co-hosts — a mix of leaders in science, academia, sports, media, and comedy — grill the guests, and by the end we’ve all gotten a bit smarter. Each episode has a new topic, a new co-host, and new guests. There’s also a real-time human fact-checker to keep everyone honest. Think of the most crackling dinner-party conversation you’ve ever heard. Produced in association with Stitcher.
