Just as a point of clarification, having spent a lot of time in mental health facilities, I'd like to point out the common confusion between Schizophrenia (a.k.a. paranoid-delusional) and DID (Dissociative Identity Disorder a.k.a. Multiple Personality Disorder). People all over seem to think schizophrenia has something to do with multiple personalities, but this is simply not true in the least. Any "additional" personalities are created external to the patient and cannot directly control his/her actions (but may influence them just as a real person could).
If you've seen "A Beautiful Mind" then that is an example of schizophrenia.
Since you're stuck on this random quote thing, could you tell us the deeper meaning behind the quotes that used to be on the home page banner of the board before Pervert of the Month took their place? I seem to recall one by Woody Allen being up for a while...
