Subtitles? We don't need no stinkin' subtitles!

This clip is quite old now, but I was reminded of it while watching Food Network Challenge, where they had five teppanyaki chefs compete in a contest in Hawaii. One of the contestants was a chef who was born in Vietnam, but had been living in the US for quite some time. Whenever he spoke on screen, there would be subtitles, despite the fact that he was speaking English, while no subtitles appeared for anyone else.
