Tech support back in the day.
Found this on the web. Since I'm trying to back into IT, this is a very funny thing and it shows that ANY upgrade of technology always confuses a lot of people. Enjoy.
UPDATE: Sorry, but the poster of this video pulled it off YouTube. What the subject of the video was this guy was upgrading from scrolls to a bound book, and was having trouble getting his mind around the idea of flippable pages. The conversation was a direct correlation between then and now, just swap "book" for your favorite software. My favorite part was when the guy closed the book after the last page. Then he tried opening it by the spine, and of course he got nowhere.
