"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. "I guess it just leaves an impression." 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?"

Funny as all get out!

Funny.  But I couldn't help thinking that in this case shouldn't the M have been on her belly!
