Engineers were sitting about discussing what kind of an engineer God was.
One thought God must be a mechanical engineer. "Look at the skeleton and musculature... a pure genius on mechanical design."
A second argued that God must be an electrical engineer. "The nerve system is well beyond the most advanced electrical systems we have ever developed, and the brain is the most advance computer on the planet."
A third argued that God is a civil engineer. "Who else would put a sewage disposal system in the middle of a recreational area ?"
