Three engineers, mechanical, electrical, and civil, were sitting in a bar arguing about God.
The mechanical engineer says "It's obvious God is a mechanical engineer. Look at the human body. Look at all the joints, tendons, and muscle systems. Only an ME could figure all that out so that we walk upright."
The electrical engineer takes a drink and rolls his eyes. "You're wrong. God is an electrical engineer. Look at the human body! You've got neurons firing, nerve cells, signal transfers, only an EE could have even come up with that."
The civil engineer finishes off his beet and laughs. "You're both wrong. God's obviously a civil engineer. Look at the human body! Who else but a CE would run a toxic waste line through a recreation area?"
