Okay, so this game is simple. One user will post 2 choices, and the next poster chooses one and posts two choices. This game is quite popular on forums, but in case you haven't heard of it here is an example:
Poster 1: Bacon or Butter?
Poster 2: Bacon. Mushrooms or Flowers?
Poster 3: Mushrooms. Cars or Trains?
... and so on. Since I'm the first one to post, I'll start.
