A young woman visits the doctor for a routine checkup. As she unbuttons her blouse, the doctor notices a faint red “H” imprinted on her chest.

Curious, he asks, “How did you get that mark?”

She blushes. “Oh, that? My boyfriend went to Harvard. He’s so obsessed with the school that he refuses to take off his Harvard sweatshirt—even when we’re making love.”

The doctor chuckles politely and moves on.

A few days later, another woman comes in. She too removes her blouse for examination, revealing a blue “Y” on her chest.

Again, the doctor asks, “How did you get that mark?”

With a sheepish grin, she replies, “My boyfriend goes to Yale. Same deal—he never takes off his Yale sweatshirt. Even in bed.”

Amused by the coincidence, the doctor shrugs it off.

But the surprise isn’t over yet.

Later that week, a third patient walks in. As she disrobes, the doctor notices a green “M” imprinted on her chest.

“Let me guess,” he says, half-laughing. “Your boyfriend’s from Michigan?”

The woman smirks and replies, “Nope. I have a girlfriend from Wisconsin.”

The doctor blinked, paused… and then nodded slowly.
“Well,” he said with a grin, “that definitely explains why the ‘W’ was upside down.”
