In this book you'll find an incredible amount of good lines to use when those inevitable accidents happen. No matter how experienced a performer you are (magician, MC, speaker, comedian) you will face situations from time to time where you need something to save the moment. It's not a question of IF it will happen, it's a question of WHEN it will happen.
You face a heckler, you drop something, you make a mistake, you hear a noise off stage, a baby cries, etc., knowing exactly what to say at the appropriate moment will show the audience that you are a real professional.
