Just Pregnant (joke)...

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, the husband 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."

Might be me, but I don't get it...

As the baby grows and the mother's stomach gets bigger and stretches, she'll be able to read the words from the stamp (that's ink stamp, not postage stamp) because it will get bigger.

FOJMO, don't feel bad, sometimes I don't get stuff either. They sometimes call me the dimmest bulb in my family's marquee.

***********, when I saw it was a joke from you, had to read it. I got it and it was hilarious.
