This summer spectacular, recorded outdoors in New York City’s Central Park, is a jam-packed show. The Office’s B.J. Novak hits the puzzle hotseat for a Shakespearean pop quiz, Wet Hot American Summer filmmaker David Wain flaunts his movie trivia prowess, and Kurt Andersen, host of PRI’s Studio 360, stakes his claim as a literary romantic. Plus, a ukulele-strumming Nellie McKay joins Jonathan Coulton to sing the catchiest songs of summers past, and NPR Puzzlemaster Will Shortz tries to stump contestants with a doozy of a final anagram showdown.
