Powerpoint Interview Presentation

As part of my second interview I am required to give a 10-15 minute presentation on any topic. I was told just to reuse one of my old presentations. The position I am up for involves a great deal of training so i decided to use part of my Robotic Training Program. I was wondering if anyone could offer any suggestions on how to add a bit of humor or interest into the beginning of the presentation.

You could dress up as a robot or you could bring in a robot (like a lego mindstorms) as a prop.
