So the Pope visits Queen Elizabeth II...

... and she says : "Watch, Francis! With a wave of my hand, I can make every loyal subject go completely hysterical!" So she waves at the crowd and every loyal subject goes completely apeshit. So Francis tells her : "Well, Elizabeth, with a wave of my hand, I can give every Scotsman and Irishman eternal joy!" And she replies : "I'd like to see that!" .... So he slaps her.
