There not fond of rules, and they have no respect for the status quo, you can quote then, disagree with them, glorify or vilify them, about the only thing you can't do is ignore them.  Because they change things. They push the human race forward. And while some may see them as the crazy ones, we see genius. Because the people who are crazy enough to think they can change the world are the ones who do.</p>
