An engineer, a lawyer, and a physician were having
an argument about which of their professions was
the oldest.

The physician said, it says in the good book that
God took a rib from Adam's side which he used to
make Eve.  That was surgery, so mine is the oldest
profession.

The engineer said, just a minute, look before this
happened God created the heavens and earth from
the chaos.  So engineering is the oldest
profession.

The attorney said, and who created the chaos.
