Sounds like someone is/has going to say/said: "Make it so, number one"
There are some good links off of this article about the color Magenta, (like, uh, who knows what 'cyan' or 'magenta' are anyway? So I looked it up. Refilling my printer cartidges required an explanation.) http://en.wikipedia.org/wiki/Magenta Dennis Gearon Signature Warning ---------------- EARTH has a Right To Life, otherwise we all die.
