I'm strongly reminded of the old joke where someone dies and goes to heaven. An angel welcomes him in and leads him to the appropriate area of heaven for his religion. On the way there, the angel is chatting and joking with people they pass in the Hindu area, the Muslim area, the Baptist section and so on, but as they approach a big walled off area the angel tells the new arrival that they must be quiet until they are past it.
Eventually they arrive at the correct section and the angel issues the new arrival his harp and wings, gets him signed up for music lessons and introduces him to his new neighbours. Before saying goodbye he asks if the new arrival has any questions:
NA: Just one, why did we have to be quiet going past that walled off area?
Angel: That's where the Catholics are
NA: But why did we have to be quiet?
Angel (whispering and giggling): They think they're the only ones here!
