Pirate Robot Ninja
From IRC Improv Wiki
As an improv comedian: are you a pirate, robot or ninja? Know your type so you can appreciate your strengths while also focusing on what you have left to learn. This book is 200 pages of lessons, exercises and metaphors designed by two teachers and performers from the Upright Citizens Brigade Theatres in New York and Los Angeles. Also, it's written as a fable where you are an "improv seeker" in an mysterious dojo hidden in the mountains. That's pretty fun! "Billy and Will love to do the 'make'em ups' and they're quite good at it as well. I would read this book...if I could read."
