Four engineers are arguing over who designed the human body.
The mechanical engineer points to the ways the bones, the muscles, and the tendons are joined together and move so smoothly and efficiently, and claims it must have been a mechanical engineer.
The electrical engineer diagrams the central and peripheral nervous systems and maintains that it would take an electrical engineer.
The hydraulic engineer insists that only a hydraulic engineer could be responsible for the circulation of the blood and the secretions of the many glands.
They look to the civil engineer and he says, "Don't look at me. No civil engineer would ever put a sewer outlet next to a recreational area".
