Three engineers were huddled together discussing the nature of God.
The mechanical engineer said he was sure that God had to be a mechanical engineer. Why, just study the perfect harmony of the human body's movement and the way that the bones fit together; and how the muscles and ligatures formed the perfect pulley system.
The electrical engineer said no way was God a mechanical engineer. God must be an electrical engineer. Just look at the way the central nervous system worked together with impulses passing along and crossing synapses and besides without this marvelous electrical feat the bones and muscles would not work.
Well, the civil engineer said that the one thing he did know was that God was NOT A CIVIL ENGINEER, because no self-respecting civil engineer would have located the waste disposal facilities next to the recreational facilities.
