An engineering student is walking on campus one day, when another engineer student rides up on a shiny new motorcycle.

"Where did you get such a functional bike?" asked the first.

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, spread her arms wide and said: "Take what you want."

The second engineer nodded approvingly: "Good choice; the clothes probably wouldn't have fit."
