Technically Funny Comedian Don McMillian has a very funny bit about How NOT to Use PowerPoint. I've seen Don perform live at a conference I attended and was very impressed with him and his material. I'll never forget his binary high five bit... very funny.
This video clip is a must see for all presenters, be it a conference presenter, user group presenter, Code Camp presenter, or just someone who delivers presentations as part of their job. Enjoy!!
