With the help of a fertility specialist, a 70 year old woman has a baby. All her relatives come to visit and meet the newest member of their family. When they ask to see the baby, the old woman says, Not yet.

A little later they ask to see the baby again. Again the mother says, Not yet.

Finally they say, When can we see the baby?

And the mother says, When the baby cries.

So they ask, Why do we have to wait until the baby cries?

The new mother says, I forgot where I put it.
