The young lady entered the doctors office carrying an infant.

Doctor, she explained, the baby seems to be ailing. Instead of gaining weight, he lost three ounces this week.

The medic examined the child and then started to squeeze the ladys breasts. He then unbuttoned her blouse, removed the bra and began powerfully sucking on one nipple.

Young lady, he finally announced, no wonder the baby is losing weight, you havent any milk!

Of course not! she shrieked. Its not my child, its my sisters!
