Here's my favorite bicycle joke:
Two engineering students, Bob and Ed, are riding their bikes. Bob says to Ed, "That's a nice bike; is it new?" Ed replies, "Well, that's an interesting story. I was walking on campus the other day, and a beautiful woman rides up to me, gets off her bike and puts it on down, takes off all of her clothes and throws them down, and says 'Take what you want.'" Bob says to Ed, "Good choice; the clothes wouldn't have fit you anyway." :p
