A doctor starts work at a college medical clinic one day. His first patient is a young co-ed.
"Doc, I have this rash on my chest, you have anything for it?" she says.
He tells her to take her shirt off and asks, " I have this rash cream but I have to ask, how did you get a rash in the shape of the letter B?"
"Oh, my boyfriend goes to Brown and likes to do it with his college sweater on." she says.
"Ok" he says and gives her the cream.
The next day another girl comes in and she has a rash on her chest too.
"How did you get a rash shaped liked the letter H" he asks.
"My boyfriend likes to do it with his college sweater on and he goes to Harvard"
He laughs and gives her the cream.
The next day another girl comes in and says, "Doc, i have this rash on my chest"
The doc shakes his head and sighs and says "ok let me see"
She takes her shirt off and he looks at the rash and says, "Let me guess, your boyfriend goes to Michigan"
She says, "No but my girlfriend goes to Wisconsin"
