A girl walked up to the information desk in a hospital and asked to see an "upturn."
"I think you mean the intern, don't you?" asked the nurse on duty.
"Yes," said the girl. "I want to have a contamination."
"You mean examination," the nurse corrected her.
"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."
