Apparently, MTV has a show called StandIn where they substitute people for the day. In this episode, Bill Gates stands in on an intro to programming class. It's a pretty short video, but I found it really cool to see the reaction of the kids in the class.
Back when I was in school, some of my prof's could have used a permanent stand in. Even if the only person they could find was the lady from the cafeteria, it would have been a better and more productive class. :roll:
