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