Engineer's folding bike (joke)
Two engineering students met on a university campus and one said, "Wow! Where did you get such a great folding bike?"
The second engineer replied, "Well, I was walking along yesterday, minding my own business, when a beautiful woman rode up on this bike, threw it to the ground, took off all her clothes and said, "Take what you want."
The second engineer nodded approvingly and said, "Good choice; the clothes probably wouldn't have fitted you anyway."
Ooh, thats a darned good one, I'm in software engineering, but the same principles apply ....
That tickles my funnytube.
