How about at the end of ROTJ, when Anakin's mask is off, he says "Yessss!!"

You mean like this?:

YES MAN, starring Darth Vader

I think Darth Vader should yell "Nooooooooooooooooo" a lot in the OT.
The Death Star blows up. Vader in his spiraling fighter: "NOoooooooooooo!"

Millennium Falcon jumps to warp, just escaping the Empire's grasp off Bespin: "Nooooooooooo!"

Vader can't find Obiwan's body after the killing blow. "Noooooooooooooo!"

Luke lets go and falls down the chute at Cloud City, foiling Vader's plan to convert him to evil. "Nooooooooooooo!"

Tarkin orders Vader to stop choking Ozzel. Would our antihero really say "As you wish"? On the contrary: "Nooooooooooooooooooooo!"

I think this would be fairly easy to do, as opposed to a lot of the other ideas on here. C'mon guys, what are the worst edit ideas that could actually be done?
