A woman and a baby were in the doctor's examining room, waiting
for the doctor to come in. The doctor arrived, examined the baby
and determined that it had a fever and was also hungry. The doctor inquired as to whether the baby was breast-fed or bottle-fed.

"Breast-fed" she replied.

Well, strip down to your waist," the doctor ordered. She did.
He pressed, kneaded and pinched both breasts for a while in a
detailed examination. After stopping to take some notes, he pressed, kneaded and pinched both breasts some more. Finally he quit,
took more notes, and told her, "No wonder this baby is hungry.
You don't have any milk."

"I know," she said, "I'm his Grandma, but I'm glad I came"
