Jokes, stories, anecdotes, and illustrations

• Don’t tell a joke to warm up the audience. A joke must be directly related to your subject matter.
• Don’t tell jokes in a business presentation. Your audience is looking for information not entertainment. This doesn’t mean that presentations shouldn’t be palatable and made with a sense of showmanship. They should be.
• Don’t ever tell jokes if you can’t do it well. Very few people can.
• Don’t tell a joke, story, anecdote or use an illustration if it will offend anyone in your audience because of its language or subject matter. Only Irish people should tell jokes or stories about the Irish. Only women etc.

You can antagonise and lose an audience if you don’t follow this advice.
