Speaking of Shakespeare and Monty Python... were you aware the Holy Grail dvd has subtitles "for people who don't like the film." They're taken from one of Shakespeare's plays but actually seem to somehow accurately paraphrase the real movie lines.

EDIT: Obi-Wan’s eloquent manner of speech really comes through in Backstroke-style subs (using Babelfish)

Regarding Anakin: “I hoped he does not attempt any to be stupid.”
Requesting to see Fett: “I should extremely like the present meeting this for to receive an award capture the fleeing criminal.”
Complimenting Fett: “Your clone is the unusual impression profound. You must be extremely arrogant.”

Are you sure you got that from babel fish? It doesn't sound any different from most of the dialog in Hack of the Clowns.
Is your English subtitle track for the entire film or just alien dialog?
