With the help of a fertility specialist, a 60 year old grandma has a baby.
All her sons daughters and grandchildren come to visit and meet the newest member of their family.
When they ask to see the baby, the 60 year grandmother says, "Not yet."
A little later they ask to see the baby again. Again grandmother says, "Not yet."
Finally they say, "When can we see the baby?"
And the grandmother 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."
