Join us in one of America’s oldest urban centers for a show about cities, including ruins, sewage and ghost towns. Our panelists are: Ed Glaeser, Harvard economist and author of Triumph of the City, who doesn’t know when to quit. Amy Glasmeier, professor of economic geography and regional planning at MIT and creator of the Living Wage Calculator, who loves to run as a write-in candidate. Eugene Mirman, comedian and the voice of Gene on Bob’s Burgers, who is kind of a big deal in Boston. Our real-time fact-checker is Mike Maughan, head of global insights at Qualtrics.

Major Garrett, Alexandra Petri and Robby Mook are panelists in Washington, D.C. The CBS Chief White House Correspondent, the Washington Post humor columnist, and Hillary Clinton's campaign manager step out of the swamp for some more light-hearted politics: from foreign cars to the last state in the union. Femi Oke is fact-checker.

Steve Levitt, Scott Turow and Bridget Gainer are panelists. For the "Freakonomics" co-author, the attorney and novelist, and the Cook County commissioner it's "game on!" as they tackle competition of all kinds: athletic, sexual, geopolitical, and the little-known battle between butter and margarine that landed in the Supreme Court. WBEZ's Tricia Bobeda, co-host of the "Nerdette" podcast, is fact-checker.

Steve Levitt, Eugene Mirman, Alexandra Petri, Che “Rhymefest” Smith and Major Garrett are among this season's stars. Here's a taste of what you'll hear in our new season. We've got 10 new episodes — one a week — beginning June 4th.

Danny Goldberg, Faith Salie and David Hajdu are panelists. The record executive, the comedian/journalist and the music critic face the music, including industrial instruments, female composers and the all-important bridge. Our real-time fact-checker is Dan Zanes, accompanied by his live band.

Tim Harford, Carla Hayden and Rahmein Mostafavi are panelists. The "Undercover Economist," the Librarian of Congress and the comedian join TMSIDK in Washington, D.C. — the city that wants to be a state — to learn about wannabes, from international spies to new human organs. Femi Oke is fact-checker.

John Fugelsang, Tami Sagher and Aman Ali are panelists. Who better to help us talk through religion than these three comedians? We look into unholy fruit, religion in banking, and the politics of reincarnation. A.J. Jacobs is fact-checker.

Brian Koppelman, Cheryl Dorsey, and Hari Kondabolu are panelists. The TV/movie producer, the social entrepreneur, and the comedian/podcast host follow the money, from the Brooklyn Bridge to Ethiopia. A.J. Jacobs is fact-checker.

James Altucher, Miki Agrawal and Aasif Mandvi are panelists. The investor/author, the controversial entrepreneur and the comedian dive deep into things that don’t work as well as they should; ideas that should have been killed off long ago; and inventions great and not-so-great. Sean Rameswaram is fact-checker.
