Sister Catherine was asking all the Catholic school children in fourth grade what they want to be when they grow up. Little Sheila said, "When I grow up, I want to be a prostitute!" Sister Catherine's eyes grow wide and she barked, "What did you say?!" "A prostitute!" Sheila exclaimed. Sister Catherine breathed a sight of relief and said "Whew!..... Thank God! I thought you said 'A Protestant'!"
