A woman in her early twenties goes into the doctor's office for a checkup. As she takes off her blouse, the doctor notices a red "H" imprinted on her chest.

"How did you get that mark on your chest?" the doctor asks, puzzled.

The woman sighs and says, "Oh, that. My boyfriend goes to Harvard, and he’s so proud of it that he insists on wearing his Harvard sweater all the time. Even when we... you know."

The doctor nods knowingly. "Ah, so the ‘H’ got imprinted from the sweater fabric?"

"Exactly," she says.

A few days later, another young woman comes in for an exam. As she undresses, the doctor notices a bright red "Y" on her chest.

"Let me guess," the doctor chuckles, "your boyfriend goes to Yale?"

The woman blushes. "Yeah! How’d you know?"

Later that same week, another patient comes in—a burly guy with a large red "M" burned into his chest.

The doctor shakes his head, laughing. "Okay, let me take a wild guess—you have a girlfriend at Michigan?"

The man looks confused for a moment and then sighs. "No, Doc… my boyfriend goes to Wisconsin."
