NPR isn't necessarily known for comedy, but one program in particular - Wait Wait... Don't Tell Me! - definitely breaks that mould. This week we speak with Wait Wait's funny and charming host Peter Sagal about his unlikely beginnings in public radio, the role of comedy in politics, and about being a subversive overachiever from early on.

Part two of our wide-ranging interview with Ira Glass.  In this second half of the conversation, Kevin speaks with Ira about anxiety, climate change, the role of storytelling in the wider world, and how it feels to look back on almost 20 years of This American Life.
