The reason that we are willing to give a speech is because we understand  the importance of public speaking and we want to be able to connect  with our audience. We want the words that we say to change their world.  

There are a number of different ways to go about doing this and each  one of them has their benefits and distractions. However, one of the  most powerful ways to ensure that your next speech will be remembered is  to add humor to it.  

If you can get your audience to laugh with you during your speech, then  there is a good chance that they’ll remember what you told them.
