Three engineers were standing around talking one day bragging. One says, "You know, I'll bet God must be like a mechanical engineer. Look at our joints, how we're constructed... how much stress they can take. It's amazing!" "Na", says the second engineer. "He must be more like an electrical engineer. Look at our nervous system. It's unbelievable!" "No way", says the last engineer. "God must be more like a civil engineer. Why else would he build us with a large waste pipeline going right through a major recreational area?"
