Unexpected...

On the web the other day, I read an article about a giant prehistoric whale skull that had been discovered. The teeth were 15" long! I called Duncan over to the computer to show him. I grabbed a tape measure and we discovered his forearm from elbow to finger tips was exactly 15" I exclaimed, "Look how huge those teeth are!" He replied, "I wish we had one, we could put it under our pillow and then maybe the tooth-fairy would replace it with a gold bar!"
