A woman went into a doctor's office with a baby. She's taken into an examining room and waits for the doctor.
The doctor examines the baby, and finds him not gaining much weight and asks the woman, "Is he breast fed or on the bottle?"
"Oh... he is breast fed!" replied the woman.
"Well then, strip down to your waist," orders the doctor.
She takes off her top and bra and sits on the examining table. The doc starts pressing, kneading and pinching both breasts for quite a while in a very detailed and thorough examination.
After a few minutes of this, the doctor motions to her to get dressed, then he says - "No wonder this baby is so hungry. You don't have any milk!"
The woman responds with a wry grin, "Well of course I don't."
"Why is that?" Asks the doctor in surprise.
"Well, I'm his aunt, but I'm SURE GLAD I brought him in today!"
