Two Tail Cast On

Can someone pls explain the Two Tail Method for casting on? Also, if there is a good video or photos to help explain the method, that would be great. Or maybe an alternative method that comes out the some in the long run? Thanks!

I think this website gives a fantastic video-explanation actually. Here is the link http://www.knittinghelp.com/knitting/basic_techniques/ It the first one on the list.

Amy has video here.
