My favorite uncle told this joke about a week before he passed away. He did it with a thick Irish brogue.
A priest and a nun were talking and the priest said, “Sister, if you hadn’t been a nun what do think you would have been?” The nun thought for a minute and said, “If I hadn’t been a nun I probably would have been a prostitute.” The priest was shocked and said, “Now sister I don’t think I heard you quite right. I’ll ask you again. If you hadn’t been a nun what would you have done with your life?” The nun turned to him and said, “Father if I’ve told you once I’ve told you a thousand times if I hadn’t been a nun I would’ve been a prostitute.” The priest said, “Oh thank me stars. For a minute I thought I heard you say you would have been a Protestant.”
