I really like this joke ( Am a doing a MEng in Civil Engineering at the mo)
A bunch of engineers are sitting around at a party, discussing the nature of the God, and who designed women.
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. "
