Plot hole: In the scene when Lisa and Akim are walking up to Akim's door (when Semi is sitting in the hot tub after fixing up their room), they are carrying groceries for Akim to cook Lisa dinner, however when Akim walks into the room (and every shot from inside the room) there is no kitchen for him to cook.
Prince Akeem: So, you would share your bed, and your fortune, with a beautiful fool?
Semmi: That is the way it has always been with men of power. It is tradition.
Clarence: I met Dr. Martin Luther King Jr. one time.
