A bunch of engineers are sitting around at a party, discussing the
nature of God.
The mechanical engineer states that God must also be a mechanical
engineer because "if you look at all the pulleys and levers that drive
the body, how the tendons and muscles and bones all work together,
well, it's just amazing."
The chemical engineer says that no, God has to be a chemical engineer
because "if you look at all the chemical processes that drive the body,
how the hormones and the brain and the glands and everything else all
interact, well, it's just astounding."
The electrical engineer says that no, God has to be an electrical
engineer because "if you look at the circuitry of the body, how the
thousands upon millions of nerve cells transmit signals from one part
to another, well, it boggles the mind."
The civil engineer speaks up last of all and says, no, God is
definitely a civil engineer, because "only a civil engineer would run a
sewer through a playground."
