A girl goes into the doctor’s office for a checkup.As she takes off her blouse, the doctor notices a red ‘H’ on her chest. How did you get that mark on….your chest?” the doctor asks, puzzled.

The girl sighs and says, “My boyfriend goes to Harvard. Every time he hugs me, the ‘H’ from his varsity sweater presses into my skin.”The doctor nods and says, “Ah, that makes sense.”

The next day, another girl comes in with a red ‘Y’ on her chest.”Let me guess,” the doctor says, “Your boyfriend goes to Yale?” She smiles. “Yep!” Later that week, a third girl walks in with a big red ‘M’ on her chest.

The doctor raises an eyebrow and says, “Let me guess, your boyfriend goes to—” She cuts him off and says, “No, but my girlfriend goes to McDonald’s.”
