Put yourself in the position of an audience member, both during the writing of your oral report and during the delivery. Those listening to your oral report want you to succeed at it, if only for selfish reasons, such as not wanting to be bored and/or disappointed. Think about speeches and presentations that have grabbed your attention in the past and make a note of what it was that got your attention.
Start your oral report with an appropriate and relevant joke or personal anecdote. This will hook your audience and maintain their attention during your presentation, whereas a lifeless introduction will make them tune out for the remainder of the report. Test your personal anecdotes or jokes on honest friends who will tell you whether they are funny, make sense, are relevant and whether they are appropriate.
Include humorous visuals in your oral report. These can be topic-relevant cartoons, photos or illustrations projected on an overhead screen. The intermittent use of humorous visuals can be particularly effective in breaking up blocks of spoken dialogue without coming across as overly irreverent to your professors, employers or colleagues.
