Where does this chicken roost...?

Check the movie Malcolm X. It comes from an infamous quote by Malcolm X. After JFK was inated; Malcolm X uttered that phrase. As a result, the Honorable Elijah Muhammad censured him for 90 days. So when the Reverend Jeremiah Wright makes that reference he knows that what he is saying is wrong. Everyone who's really listening knows its wrong but he's saying it to purposely be controversial.
