If you do end up doing this, make sure that you guys aren't measuring with just regular rulers. They are very inaccurate, since so much is based on where the person places the starting point of their measurement. I patented a penis measuring tool that is the only way to guarantee that all measurements are consistent and taken from the exact same spot. It also prevents anyone from cheating. I would be happy to sponsor your "event" and send out a penis measuring kit for everyone who will be there. The product is called "The Final Say" and the patented device is called a "phallumeasure." You can see it at www.sizeofaman.com if you want to check it out ahead of time.
