Three Engineers A mechanical engineer, an electrical engineer and a civil engineer are sitting around and talking about God. The mechanical engineer says, "God is a mechanical engineer. Just look at the human body - a light-weight skeleton with moving parts holding up a massive frame of muscle and fat. God must be a mechanical engineer!" The electrical engineer disagrees. "No, no. God is an electrical engineer. Just look at the human body - the nerve system routes electrical signals to the brain which is essentially a computer. God must be an electrical engineer!" The civil engineer disagrees. "No, no. God is a civil engineer. Just look at the human body - only a civil engineer would run a toxic waste pipe through a playground."
