A girl goes into the doctor's office for a checkup. As she takes off her blouse, he
notices a red "H" on her chest. "How did you get that mark on your
chest?" asks the doctor. "Oh, my boyfriend went to Harvard and he's so proud of
it that he never takes off his Harvard sweatshirt, even when we make love," she
replies. A couple of days later, another girl comes in for a checkup. As she takes off her
blouse, he notices a blue "Y" on her chest. "How did you get that mark on
your chest?" asks the doctor. "Oh, my boyfriend went to Yale and he's so proud
of it that he never takes off his Yale sweatshirt, even when we make love," she
replies. A couple of days later, another girl comes in for a checkup. As she takes off her
blouse, he notices a green "M" on her chest. "Do you have a boyfriend at
Michigan?" asks the doctor.
"No, but I have a girlfriend at Wisconsin. Why do you ask?"
