Two university professors, one pushing a bike, were walking across a university campus when the other said, "Where did you get such a great bike?"
The second professor replied, "Well, I was walking along yesterday, minding my own business, when a beautiful woman rode up on this bike, threw it to the ground, took off all her clothes and said, "Take what you want."
The first professor nodded approvingly and said, "Good choice; the clothes probably wouldn't have fit you anyway".
