Three freshman engineering students were sitting together at lunch time, when one brought up the question of who designed the human body.
One of the students insisted that the human body must have been designed by an electrical engineer because of the perfection of the nerves and synapses.
Another disagreed, and proclaimed that it had to have been a mechanical engineer who designed the human body. The system of levers and pullies is ingeniuos.
"No," the third student said "your both wrong. The human body was designed by an architect. Who else but an architect would have put a toxic waste line through a recreation area?"
