Kakashi is always late, has a stupid excuse, and reads girlie books non-stop. He's definitely a goofball. In fact, now that you mention it, the only crazy-strong guys who were serious were bad guys - not a single one was good.

However, I still think Tobi's original personality was an act to fool the Akatsuki. For what reason, I have no idea, but that's what I think right now.
