This week, the hosts of the Slate podcast ICYMI, Rachelle Hampton and Candice Lim, stop by to play our new game, Burden or Delight? We consider the Army’s new tactical bras, smartphone location sharing, and Fall Out Boy’s updated version of Billy Joel’s classic “We Didn’t Start the Fire.”

Then, we dive into the Guinness Book of Records. Journalist and author Imogen West-Knights tells about how the company known for the world’s most odd and outrageous titleholders has lasted for over half a century.

Plus, Amy Brady unpacks the surprising history of ice. In her new book Ice: From Mixed Drinks to Skating Rinks–A Cool History of a Hot Commodity, she argues that the ice industry transformed the United States in ways that might surprise you.
