The Frozen Wastes Of Hoth...

Luke Skywalker, having just escaped the Wampa's cave has collapsed unconscious and is near death.

BEN : Luke! Luuuke!

LUKE : Ben? Benn?

BEN : You will go to the Dagobah system!

LUKE : Dagobah system?

BEN : There you will learn from Yoda

LUKE : The Jedi Master who instructed you?

BEN : Well..*sigh* he gave me a few lessons when I was really little. My Jedi Master is like myself a ghost but you won't hear or see him so Yoda will do the training.

LUKE : So who's Master was he?

BEN : He taught the Sith Lord who chopped your father's arm off and started the Clone Wars.

LUKE : Well...I'm sorry but this Yoda guy isn't instilling with with much confidence and I don't like the sound of have any of my limbs getting cut off.

BEN *rolls eyes*

LUKE: What?

BEN : Nothing!

LUKE : So who is this Sith Lord guy, Darth Vader?

BEN : No I've already told you I trained Darth Vader...Dooku...Count Dooku he died about the same time as your father.

LUKE : Heard that one before.

We should expect this line to appear in the next Special Edition of Star Wars, known as "The Star Wars Special Limited Deluxe Director's Cut Edition Of The Original Special Edition".
