Johnson quotes several Presidents of the United States (as well as a few other American historical figures including "Live Free or Die" from Revolutionary War General John Stark) during his run for Congress speech. "We have nothing to fear but fear itself" Franklin D. Roosevelt; "Ask not what your country can do for you, ask what you can do for your country" John F. Kennedy; and "Read My Lips" George Bush (George H.W. Bush, #41).
In the scene between Eddie Murphy and Charles S. Dutton eating crab in Baltimore, they are inauthentically eating Dungeness crab (latin name 'Metacarcinus magister' named for Dungeness, Washington State, USA), which is found only on the Pacific coast of North America. The Baltimore, Maryland area is world renowned for their Chesapeake blue crab or Atlantic blue crab (latin name Callinectes sapidus) which is a species of crab native to the western Atlantic Ocean and especially concentrated in the Chesapeake Bay of Maryland, where it is culinarily significant and economically crucial, the Maryland state crustacean, and an extensive fishery. The Chesapeake blue is an entirely different species from Dungeness, and typically eaten exactly as shown in the film, however Dungeness crabs are not eaten that way.
