Basically, we start with Kevin Bacon and then name a movie he's in and another actor who's also in that movie. Then the next person names a movie that that actor is in and another actor who's also in THAT movie. Then we just keep going, one post at a time. No double posting, no repeating actors (repeating movies is fine), and no TV shows. The game is over if we ever get to a point where no one can make a move without repeating an actor. Trust me, that never happens.
Ready? Go!
Kevin Bacon was in Animal House with John Belushi.
