Are you one of those folks who hyperlinks from PowerPoint to YouTube when you want to share a video with your class? And do not say, you are one of those schools that disallows YouTube. If the Smithsonian can have its own YouTube channel, certainly you should be able to access it, right? I think that is in the United States Bill of Rights. Or, it should be.
Anywho, this 4+ minute video will teach you (or your students or colleagues) how to embed YouTubes right into PowerPoint 2007 so you look uber-professional (if you have PowerPoint 2010, try one of these tutorials). Can you believe this particular tutorial above has over a million views! Most of those views came from my amazing college students. Yep, future tech-savvy educators.
