A brunette gives birth to a beautiful baby girl. The baby has a few little blond hairs on her tiny head. The mother takes a brown marker and colors the baby's head brown.
When the doctor who delievered the baby comes back into the room he shouts, "What in the world happened to that baby?"
And the brunette mother says, "I fixed her up, now when she goes to school she can hear all these blond jokes and come home and tell them to me."
