Re: Why didn't Kirk just contact Sulu?
Perhaps the UT could be recognized as *specifically Starfleet* because of a pattern in the word choices it would make. Perhaps they wanted a bad translation so the Klingons would think they were a smuggler ship.
Or maybe it is completely idiotic to think that Uhura can't speak Klingon, and it was a dumb comedy bit.
As the brilliant philosopher once said... Everybody, have fun tonight. Everybody, Wang Chung tonight.
