Three freshman

Three freshman engineering students were sitting around talking between
classes, 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 exclaimed that it had to have been a mechanical
engineer who designed the human body. The system of levers and pullies is
ingeniuos.
