Apparently there are some bootleg versions of Revenge of the Sith going around. The bootlegs are complete with a driect translations in English of what the Chinese intepritation of the script was. (So, it translated from English to Chinese back to English.)
Someone who purchased this bootleg copy, made this nice little slideshow of some of the funnier captions in the movie.
This actually reminds me of when Astavista (and on Search Engine—not sure if they're still around) first released translation services. A buddy of mine, Roy, and I would type up IMs and then run them from English to some language back to English and send our IMs that way. Some of the results were really funny.
