A man and his wife were making their first doctor visit prior to the birth of
their first child. After everything checked out, the doctor took a small stamp
and stamped the wife's stomach with indelible ink.
The couple was curious about what the stamp was for so when they got home, he
dug out his magnifying glass to try to see what it was. In very tiny letters the
stamp said, "When you can read this, come back and see me."
