3. Senator Hughes Approves The Human Centipede Program
After having a quick think about it, Senator Hughes has a change of heart and returns to the prison, just in time to interrupt Boss from shooting Dwight and then presumably himself. Hughes tells the two men, "This is exactly what America needs. This may even get me elected President. You've convinced me, it's genius. Don't change a goddamn thing. My pals in DC, they won't believe their near-sighted eyeballs", before leaving. So, Dr. Jones' death was ultimately for nothing, and there's no way this scene in particular isn't a giant middle-finger to American politics.
