A nun teacher at a girls' convent school was asking her class what they wanted to do when they started work.

She got all the usual responses - doctor, nurse, lawyer - until she got to Mary. "I'm going to be a prostitute, Sister, " she said and the nun fell down in a faint. When she had been revived she looked at the girl. "What did you say to me, Mary?" "I said I'm going to be a prostitute, Sister." "Oh! The saints be praised. I thought you said you were going to be a protestant!"
