Suddenly the door opened and a very pretty blue-eyed blond came in pushing an exam table on wheels. When she got it where she wanted it, she said: "Good afternoon, class. I am sorry for the delay. I know it is the very last class and I am sure you want to finish up and get on with whatever you have planned for the weekend. However, I had a bit of trouble finding this exam table but this is an important part of our class today.
