I am a professional children's entertainer, many years ago I bought a vent puppet and in the privicy of my own bedroom, spent may hours talking to it, it never talked back to me so I put him away to take out on a rainy day.
I was given this book as a present and after a lot of study with it, I now use my puppet in my act, and he has taken on a life of his own. This book is packed full of good ideas, sample scripts and of course, the rudimentary basics of ventriloquism.
When ever somebody asks me how to learn to be a ventriloquist, this is one of the two books I recomend!
