An electrical, a mechanical and a civil engineer are having lunch one day. Their conversation turns to what type of engineer God would be (as it always happens in these jokes). In any case, the electrical engineer describes the central nervous system, nerves, synapses and states that God would most certainly be an electrical engineer.
The mechanical engineer describes the bone structure, joints, muscles, etc and states that God would most certainly be a mechanical engineer.
The last gentleman states that God is most likely a civil engineer because he routed a major waste disposal pipeline through a recreational area...
