The Pope walks into a bar - he finds some guys arguing with their friend, who is a midget. "Holy crap, it's the Pope!", says the midget, "I'll ask him!"
"Sir, are there any midget nuns in America?"
"Oh, no", says the Pope.
"How about in the world - are there any of them anywhere in the world?"
"No no", replies the Pope.
"Is there even such a THING as a midget nun?"
"Of course not!", replies the pope.
His friends then burst out laughing, chanting:
Joe screwed a Pen-guin, Joe screwed a Pen-guin!"
