A nerd, a nude, and a bike
A nerd was walking on campus one day when his friend, another nerd, rode up on an incredible shiny new bicycle. The first nerd was stunned and asked, "Where did you get such a nice bike?"
The second nerd replied, "Well, yesterday I was walking home minding my own business when a beautiful woman rode up to me on this bike. She threw the bike to the ground, took off all her clothes and said, 'Take what you want!'"
The second nerd nodded approvingly and said, "Good choice. The clothes probably wouldn't have fit."
