An Atheist is driving in Northern Ireland during the Troubles...

And he gets stopped by a member of the RUC.
The gruff RUC officer walks up to the window and asks him "Catholic or Protestant?"
The Atheists looks at him and says "well I'm an atheist"
The RUC officer nods "Oh okay, but a Catholic or a Protestant atheist?"
(I have no idea what people outside Ireland know about the troubles)
