From a reader:

Sir–
You claim that God was a doctor. In fact this very same debate was
held by a doctor, an architect and a lawyer.
“Medicine,” said the doctor, “is the oldest profession. After all did
not God cause a sleep to fall upon Adam at which point he removed a
rib and fashioned it into Eve? Was this not the first operation with
anesthetic. Therefore, medicine is the oldest profession”
“Not so fast,” replied the architect, “What about a week earlier? God
created the heavens and earth from primordial choas. This was clearly
a giangantic act of design, therefore architecture is the oldest
profession.”
“Wait,” said the lawyer, “Who do you think made primordial choas?”
