How awesome would that be if Yoda was a sith master?!! Damn. And Luke thinks he training to learn the force, but Yoda's pushing towards the darkside. All part of his diabolical plan. We could add a scene after the Yub-Yub song and the Naboo celebration where Naboo blows up and Luke pulls out his saber gives into the dark side (after seeing a ghost of his dad, younger than him (hayden) and he cuts down all the ewoks in a rage like Anakin did with the sand people. Damn. Yoda a Sith Master...I like it. That better than Emperor/Senator Palpatine. Cool.
