I agree about the "Black man sitting on his porch" bit being unfortunate. In the UK, people will undoubtedly know that that part is meant to be ironic, but in the US, that will not be the case. Because Black people are already being scapegoated here in the US by people who are blaming them for the economic meltdown, I don't think it's good to be putting any more fuel on that fire. Of course, the people who made that video had no way of knowing that a year after they made the video, Black people in the US would be scapegoated for the economic meltdown in this country. But it's unfortunate that it's in there.
