These three engineers are discussing who designed the human body. The
first one says “It must have been an electrical engineer, because of all
the complex nerve endings and circuits”. The second one says “It must have
been a mechanical engineer, because of the perfect movement of the joints.
The third guy sits and thinks for a minute before finally replying “No.
You’re both wrong. It was a civil engineer. Who else would put a toxic
waste pipeline through a recreational area?”
