Edit: I didn't realise this was kinda like "Ask a stupid question, get a stupid anwser" board. So if no one really runs with it, delete it :( (Someone really needs to add a delete post/topic button...)
It's a real simple forum game in which I kick it off with a true/false question in the form of
"The person below me ________________."
Then the next person to post has to post the answer to the question (add a few tibits if they want), and then post a new question.
For example, If I post:
The person below me has a dog.
The next person posts:
True. (or false)
The person below me can swim.
And so on and so on...

So to kick off the fun with something simple,
The person below me has more than 3 pets.
