I wish this scene and the prison break scene were finished and left in the movie. It was good for the continuity. And it's interesting how Abrams sidestepped the whole "which Klingons do we use" question.
A lot of so called klingon (or any scifi martial society phraseology for that matter) has its origins in some pretty obvious sources, the two most noteable in their infamy being from the hundred years war and world war two respectively.
- Because it was a good day to dye
(Klingon phrase that actually originates from the Spanish Civil War)
