3 engineers (mechanical, electrical and civil) were discussing what the best type of engineer was. The mechanical engineer said, "Well, God must have been a mechanial engineer. Surely if you look at the human body, what with all the joints and pounding the body takes, it's clear he was a mechanical engineer." The electrical engineer speaks up, "but if you look at the nervous system, with all its intricasies, one must admit that God had to be an electrical engineer". The civil engineer finally speaks, "God must have been a civil engineer, who else would have run a water and sewer system right through the middle of a recreation area?"
