Finally, for the week of brave speeches I have something special for you. Have you ever heard of Powerpoint Karaoke?
The basic rule is simple: You have to give a presentation with slides you’ve never seen before. This video is from the inaugral McCann Sydney PPTK event and so far the best I could find: Johnny Search didn’t know in advance that he will talk about flirting.
If you haven’t had enough, there are more presentations from the same event.
