An American tourist is walking through the streets of Dublin, when a terrorist grabs him, pulls him to a side street, puts a knife at his throat, and asks:
"Are you Catholic or Protestant?"
The tourist quickly considers the options: If I say Catholic and he is Protestant, he will slit my throat... If I say Protestant and he is Catholic, he will slit my throat...
Then a solution dawns on him: "Actually, I'm Jewish."
The terrorist's face brightens up: "I am the luckiest Muslim in all of Ireland!"
