A woman and a baby were in the doctor's examining room, waiting for the doctor to come in for the baby's first exam. The doctor arrived, examined the baby, checked his weight, and being a little concerned, asked if the baby was breast-fed or bottle-fed.
   "Breast-fed," she replied.
   "Could you strip down to your waist, please," the doctor ordered.
   She did. He pinched her nipples, then pressed, kneaded, and rubbed both breasts for a while in a detailed examination. Then, stepping back, the doctor motioned to her to get dressed.
   "No wonder this baby is underweight," the doctor concluded. "You don't have any milk."
   "I know," she said, "I'm his Grandma, but I'm glad I came."
