A Mother Superior of a convent was sitting at her desk when her assistant came rushing into her office. Closing the office door, the assistant solemnly announced "Mother Superior, I have news..."
"Well, what is it?" asked the head nun.
The assistant approached Mother Superior's desk, bowed her head close and whispered, "A case of Syphilis has been found among the sisters!"
"Oh, thank goodness!" exclaimed Mother Superior. "I was getting sick of the Chablis!"
