 At the beginning of the movie, Kurt Russell (I) (qv)s character  (dressed as Elvis) steps out of a car, and a kid comes running up to  him and kicks him in the shin. This is an inside joke which refers  to _It Happened at the Worlds Fair (1963)_ (qv) in which Russell  played a kid who runs up to (the real) Elvis Presley (qv), and  kicks him in the shin.
