Unlucky

This man is walking home from the pub, through the Markets in Belfast, when a masked man steps out of an alleyway and points a gun at his head.
'Are you a Taig or a Prod?' asks the gunman.
Terrified of giving the wrong answer, the man thinks for a minute, and then says: 'I'm Jewish, actually.'
'Really?' says the gunman. 'In that case, I must be the luckiest Arab in the city tonight.'
