(This one leaked out of Microsoft the other day. I didnt save the
original)

Two male engineering students meet each other on campus. One says to
the other, Hi Bill, Where did you get that new bike? Bill replies,
Well, I was walking to class the other day when this pretty co-ed
rode up, jumped off her bike, took off all her clothes and said You
can have anything you want!

Good idea, Bills friend replied. Her clothes probably wouldnt
have fit you anyway.
