I think deciding to write and deliver funny graduation speeches is a very brave thing to do. Since we all have a real fear of public speaking, giving a difficult speech can be even worse. However the opportunity to deliver a graduation speech that is not to be missed. I believe it's a real chance to say something worthwhile at an important occasion. You may feel that there should be serious messages in your speech or decide that entertaining the audience is your purpose. If you wish to entertain a graduate audience then a humorous speech may be just perfect. However that can take a lot of work to prepare and it can be a high risk tragedy. Anyone delivering a funny speech needs to be very sure the audience will laugh. There is no point in the speech at all if the audience is silent at the moment the speaker wants them to laugh. Deciding what makes an audience laugh can be quite difficult
