This may or may not be a success, but here goes.
So the point is to come up with a topic for debate and the next person answers with what they think is the correct answer or best option, and then they give a reason for it.
Example; what came first, the chicken or the egg? The egg because egg laying creatures existed before chickens. Or alternatively, a circle has no beginning.
Another example; who's the bigger fool, the fool or the fool who follows him? The fool who follows him because he knows he's a fool yet still follows him.
A fun thing about this is you don't have to give a new topic to debate in your post, you can let the discussion continue.
Ok, first off, where do vanished objects go?
