I work as a speechwriter and I have this book close by every day. It's definitely not a work you read from cover to cover, but everyone should have a copy for the day they have to do a wedding speech or a presentation at work.
Monkhouse distils a lifetime's worth of experience into 208 pages. Little gems like, 'It's easy to tell right from wrong. Wrong is more fun.' or 'I warned the Chairman that I wouldn't have time to prepare a speech and he told me to say something off the top of my head, so - here's a short talk on dandruff.'
A lot of speechmaking is about regurgitating entertaining nonsense. You can make a patchwork quilt of Monkhouse's lines and it will work on an audience. Never trust what you think is funny yourself until you've had about ten year's experience.
The book also gives strategies for dealing with nerves and preparing your talk. The book has chapters on openings, closings and lots of longer anecdotes for the golf club or Rotary dinner.
Remember when Monkhouse lost his famous comedy books? Well I reckon this one has much of his best material.
