A woman walks into the doctor's office for a mammogram.
The Doctor says: "Take off your shirt and sit on the table."
The woman takes off her shirt and the Doctor notices an H is imprinted into her chest. When he asks her about it the woman says: "My husband went to Harvard, and when we have sex he likes to wear his jacket. After so many years of marriage, it just kinda stayed." "Oh," says the doctor, "I understand."
The next woman comes in and takes off her shirt and she has a Y in the same spot. The doctor says: "Let me guess, your husband went to Yale?" "Yes," the woman says, "how did you know?" "I'm a doctor," he says, "I'm supposed to know these things."
The next woman comes in and takes off her shirt. She has a large M, just to the side of her belly button. The doctor says, "Let me guess...You husband went to Michigan." "No," she says "Wisconsin"
