Did you see it? The geek's watch is on his left hand in the third-to-last frame, but on his right hand in the final frame. He couldn't possibly have changed it while Obi-Wan silently consulted with Yoda, since he was encumbered with popcorn and cola! I intentionally threw that incontinuity into it to satisfy all the "Star-___" geeks who watch space sci-fi just to identify all the physically impossible bits.
