Three engineers were debating: Who Designed The Human Body?
First engineer: "Must have been a Mechanical Engineer. Look at all the bones, and the muscles that move the various parts of the body."
Second engineer: "Nope, it was an Electrical Engineer. Look at all those electrical pulses that move the muscles in the body."
Third engineer: "Nah! It was a Civil Engineer.. Who else would run a waste water line through a recreational area?"
