Talking about bathrooms, i remember that in one bar of FFVII(sorry, don't remember in what city), a guy was inside a bathroom all the time! He was the entire game in that bathroom. AVALANCHE saved the world and that guy was probably, still in the bathroom. I remember that i talked with a NPC in the same bar, and he said something like "i question myself, when this guy will go out of the bathroom".
I think that in the end of DoC he is still in it.
