This sweet young thing enters a doctor's office for her annual physical. The doctor has her disrobe and sit on the examining table. Right off he notices a rash all across her chest in the shape of an "H". "How did that happen?" he asks. She says, "My boyfriend is a big football star at Harvard, and he won't take off his letter sweater when we fool around."

Strange, thinks the doctor, but to each his own. Some time later another sweet young thing enters the same doctor's office for her annual physical. Same drill disrobe, and sit on the examining table. The doctor notices an almost identical rash on this girl's chest, only this time, it's in the shape of a "Y". "How did you get this rash?" the doctor asks. The sweet young thing replies, "Oh, my boyfriend is a letter man at Yale, and he won't take his sweater off when we fool around." "Oh" says the doctor.

Not a half hour after this young lady leaves, another sweet young thing comes in for her annual physical. Again the doctor notices a rash on her chest in the shape of a giant "M". The doctor says, "Don't tell me, your boyfriend goes to Minnesota State!" "No" says the sweet young thing. "But I have a girlfriend who goes to Wellesley."
