One day, at a Catholic school run by nuns, the Mother Superior is teaching a class when the regular teacher is taken ill.

"Now, class," she says, "I'm going to go around the room and ask each of you what you want to be when you grow up."

"What's your name," she asks the first little girl. "I'm Sally," is the reply. "And what do you want to be when you grow up, Sally?" "I want to be a nurse," said little Sally.

"And what's your name," Mother Superior asks a little boy. "I'm Johnny," answered the boy. "And what do you want to be when you grow up, Johnny?" "A truck driver," said Johnny, holding up a toy truck.

This went on until she got to one naughty little girl sitting at the back of the room.

"And you up the back..., what's your name," asked the nun. "I'm Trixie," said the girl, "and when I grow up I wanna be a prostitute." Upon hearing that, Mother Superior flopped to the floor in a dead faint.

When she came to, the nun looked intently at Trixie and said slowly, "What... did... you... say?" Trixie looked just as intently back at Mother Superior as she responded, "I said I wanna be a prostitute when I grow up." "Oh, saints be praised," said Mother Superior, "I thought you said you wanted to be a protestant."
