Jason Zinoman is the comedy critic for The New York Times, and has written a new book about David Letterman which will come out April 2017. But first, Zinoman joined me once again to close the book on 2016. Who was the Most Valuable Performer in comedy in 2016? Who were the stand-out stand-ups? We discuss the year's work by Amy Schumer, Kate McKinnon, Jeff Ross, Maria Bamford, Tig Notaro, Donald Glover, Reggie Watts, Chris Rock and Louis CK, plus stars on the rise such as Rory Scovel, Kate Berlant, and John Early. And Zinoman also challenged me to define whether our current comedy boom is still booming, or whether the bubble is ready to bust. So let's get to it!
