Two engineering students meet on campus one day.
The first engineer calls out to the other, "Hey Nice bike! Where did you get it?"
"Well," replies the other, "I was walking to class the other day when this pretty, young student gal rides up on this bike. She jumps off, takes off all of her clothes, and says, You can have anything you want!"
"Good choice," says the first, "her clothes wouldn't have fit you anyway."
