To use Google’s system, the user simply types in the words “Bacon number” followed by the name of the actor. By way of example, typing “Bacon number Simon Pegg” reveals that Bacon and the British actor are linked by Tom Cruise, because the latter appeared in 1992’s A Few Good Men with Bacon and in 2006’s Mission: Impossible III with Pegg. Pegg therefore has a Bacon number of two, indicating two degrees of separation.
I would have killed for this when I was 16. Well played, Google.
