How to save youtube video without any special programs

Just found out about this interesting trick. You can save any youtube video without any additional program or plugin, just by typing "OK" in the address bar...

Example:

http://www.youtube.com/watch?v=EE2vgzTcmxI

Now type "OK" between the www. and youtube. It should look like this:

http://www.OKyoutube.com/watch?v=EE2vgzTcmxI


You can save the video now, just like that.
The file will be saved in flv format. Not the best quality but not too bad either...
