One of the best books I’ve read about comedy magic (i’m still reading it) is Be More Funny by Christopher Barnes. This book is a solid book on techniques to create comedy magic, and probably the best that breaks it down into different types of comedy.
His examples of the routines to illustrate the comedy principles are great and all of the tricks are unique. He doesn’t just take a basic trick and make it funny, he builds a whole unique routine. He’s not just doing funny patter with Hippity Hop Rabbits, but creating an original ride to take the audience on in each trick.
While reading this book I came up with the idea of a card trick with crackers. The trick is coming along, it still has a way to go. I can’t think of the last time I read a magic book and ended up with a unique routine out of it. Honestly, I think this book is one of the best $50 you can spend on a magic book. I think that even if you aren’t a comedy magician you’ll learn something out of it because it teaches you how to create your own routines, not just make existing ones funnier!
