For those of you who don't already know this download trick, one can download an existing YouTube movie clip by manually adding "KISS" into its URL. With this added text string, the background YouTube Storage System will then ask for download verification, download location and file type - for your downloaded file request. Yes. I'm serious. Entering the word "KISS" into the URL does work.
For example. Lets say you like watching (using) a Beginner Yoga YouTube clip but your workstation isn't always connected to the internet. You simply want to download (when connected) and watch the same movie when your computer is NOT connected to internet. For example, laptop connected to large screen TV via HDMI cable and NO wireless Internet connection is available.
