Three engineers were debating God one day. There was a mechanical engineer, an electrical enginer, and a civil engineer.
The mechanical enginer argued his point.
"God is obviously a mechanical engineer. Look at the marvelous way in which all the muscles, bones and organs work together, the intricacies of load, force, and energy involved in the human body. Only a mechanical engineer could have designed the human body."
Next, the electrical engineer made his rebuttal.
"God could only be an electrical engineer. Look at the complexity of the human nervous system. A massive, multi-parallel computer, the brain, controlling miles of nerves that operate all the systems of the body. Only an electrical engineer could have accomplished such a complex task."
Finally, the civil engineer put forth his theory.
"God HAS to be a civil engineer. Who else is gonna put a playground between two sewer outlets?"
