Don t settle for giving your audience just facts. In my presentation seminars I always show examples of before and after visual. And I use the company s visuals so they are personalized for them. Identify your own type of humor and use it. Some people are good at ad libs.
Some people are wonderful joke tellers.
Be careful though. Don t tell a joke unless you are sure it will work. You aren t speaking as a comedian. If you aren t good at jokes, don t tell them. And if you do tell jokes, be sure your joke will not offend anyone.
