In this latest episode of Improv Nerd, UCB's Billy Merritt talks about his new book, Pirate Robot Ninja; An Improv Fable, which he co-wrote with Will Hines. Jimmy talks to Billy about what it means to be a Pirate or a Robot in improv, the "four pillars" of doing a good improv scene, and what the "game of the scene" means to him.
