Idea stolen from ESPN's Sports Center, i'm sure we've all seen this. It's also been used on many forums all over the internet. Fact or Fiction. I, as the first person, will ask a question, a FACT or FICTION question, then, the first person to read it, anwsers it "FACT" or "FICTION", and then asks a question of their own for the next person to get.
To make this more interesting, try posting a 1-2 sentence reason behind your anwser instead of just saying fact or fiction.
