Like a zombie, or that leftover beef stew that's been in the fridge for 2 years, "The Saga" is coming back to life!
Darth Vader was not Luke's father. A paternity test by Maury Povich revealed to Vader that "You are NOT the father!". After checking six other potential candidates, including Obi-wan Kenobi, Emperor Palpatine, Bail Organa, Lando Calrissian, Commander Cody (as well as all his Lost Planet Airmen), and even Yoda, it was finally revealed that Luke's father was in fact Mace Windu. I guess Padmé had a little 'dark side' in her, too.
