Inspired a game called "Six Degrees of Kevin Bacon", whereby people have to link any given actor to him by no more than six steps. For instance, to do Fred MacMurray, you could observe that MacMurray worked with Lee Marvin in The Caine Mutiny (1954), which is one step; and Marvin worked with Jane Fonda in Cat Ballou (1965), which is two steps; and Fonda worked with Jack Lemmon in The China Syndrome (1979), which is three steps; and Lemmon worked with Bacon in JFK (1991), which completes the link in four steps. Harder versions of the game exist, limiting the player to five, four or even three steps. The original version of this game existed for numerous years and the pivot-person was then Paul Erdös, a mathematician (one's Erdös number measures the number of people a scientist is away from having authored a paper with Dr. Erdös). A very few people, mostly scientists who have appeared in documentaries (such as Carl Sagan), or actors who have also co-authored scientific papers (such as Danica McKellar and Natalie Portman), have both Erdös AND Bacon numbers.
