Great White Hype, The Easter Egg - Tell Jules I Said Hello

In a scene set in a boxing areana, Samuel L. Jackson's character is sitting down in anticipation of a boxing match. A guy walks by dressed as Vincent Vega of "Pulp Fiction" fame.
Jackson's character says (paraphrasing)"Hey, my man Vincent. Tell Jule's I said hello."
Jackson is making reference to the character, Jules Winfield, that he, himself, played in "Pulp Fiction."
