A hot coed visits a doctor for a physical. After the checkup the doctor says, “Everything looks fine, but why is an M imprinted on your stomach?”

“My boyfriend goes to Michigan,” she replies. “He loves his school so much that he wears his varsity jacket during sex.”

The next day a different coed visits the same doctor, and she also has an M on her stomach.

“Let me guess,” says the doctor, “your boyfriend goes to Michigan.”

“No, but my girlfriend’s at Wisconsin.”
