Three engineers are arguing over what kind of engineering background God must have had in order to have created the human body.
The first engineer says, "He must have been a mechanical engineer. Look at how the joints work and the hydraulics of the circulatory system!"
The second engineer says, "Nah. He was a chemical engineer. Look at the subtleties of nerve transmissions and the oxygenation of the blood."
But the third engineer says, "He was a civil engineer. Who else would put a sewer line through a recreational area?"
