"Breast fed," replied the woman.
"Strip down to your waist," Dr. Santa ordered.
The woman did as she was told and Santa examined her breasts. He squeezed and pulled each one for a while and then he sucked hard on each nipple.
Finally he remarked, "No wonder this child is suffering from malnutrition. You don`t have any milk!"
"That`s right," said the woman. "This is my sister`s child."
"Well," said the startled Santa. "I had no idea. You shouldn`t have come."
"I didn`t," replied the woman, "until you started sucking on my second breast."
