Episode III - remember when that came out, way back when? Found a new version that's been highlighted recently - a bootleg version translated to chinese, then back into english. Pretty funny, if you're into that sort of thing. Episode III: Backstroke of the West
(Not a movie, just a bunch of screenshots)
Darth Vader: NOOOOOOOOOOOOOOO!!!!!!!!
Translation : Do not want
By no means the funniest one, but certainly one of my favorite moments.
