Blonde Hospital

A girl - (I don't recall her hair colour, not that that would be important....I don't even know why I brought it up) - walked up to the information desk in her local hospital and said, "I need to see the upturn, please."

"I think, you mean the 'intern,' don't you?" asked the nurse on duty.

"Yes," said the girl. "I want to have a 'contamination.'"

"Don't you mean 'examination,'" the nurse questioned her again.

"Well I want to go to the 'fraternity ward,' anyway."

"I'm sure you mean the maternity ward."

To which the girl replied: "Upturn, intern; contamination, examination; fraternity, maternity.... What's the difference? All I know is I haven't demonstrated in two months, and I think I'm stagnant."
