Download youtube video by just adding kiss in front of the URL

Here I will give you a tip to download youtube video in an instance. While watching a certain video in youtube, if you want to download that video then you just have to put kiss in front of url (but after www). For example your url is http://www.youtube.com/watch?v=-K_8R03jIZI&feature=related then the changed url will be http://www.kissyoutube.com/watch?v=-K_8R03jIZI&feature=related or you can just go to kissyoutube.com/watch?v=-K_8R03jIZI&feature=related and follow the steps there and you can download the video in flv format. Try it, its cool ;) have fun.
