For example, Will Smith's Bacon number is 2
Will Smith and Josh Brolin appeared in Men in Black 3. Josh Brolin and Kevin Bacon appeared in Hollow Man.
Now, the search engine Google is joining the game.
You simply type "Bacon Number" into the Google search bar and then the actor's name you want to check.
So, if you type in your name and it doesn't work? Sadly, that means you're not a star. Not in the Hollywood sense anyway.
