Good quotes on importance of good network addressing

I'm doing a presentation and white paper to convince a bunch of people that network addressing is one of (if not the most) important aspect of network design and management. The goal is to convince them that we need a plan, which will probably require them to do some renumbering. I'm looking for a couple of good quotes to include in the presentation. Anyone got some good ones from some Internet/network luminaries? Something to confirm the importance of a generally boring topic. Thanks. Pete.
