I read this book, for the idea to improve my public speaking, something I have done just a few times but I thought it is a good reminder and even better trying to add humor to one presentation
The first point is to start with a story. By nature we are attracted to stories, and you need to tell it in present, like you are living it in the moment. And get the public feeling that they could be there.
Adding humor is hard bit for me, as well, depends on the time of humor you want to add, at the end of the day, I want to make good presentations, but it is clear if you add something funny, the audience will be more engaged with it and remember it!
For the jokes perspective, it is important to trim them to the max, remove the unnecessary. Three phases: Preparation, anticipation and punch line! And you need to write the jokes. This is very critical step. The most funny comedians work a lot in their set and jokes, it is all preparation, rehearsal and improvement of your lines
You need to be sure, you memorize your set, like using the memory palace method. And be familiar with the audience.
I should have taken more notes from the book, it is small and easy to read. So I should give it another go (when I have a presentation or job interview)
