A REAL VACATION

 Two priests were going to Hawaii on vacation and decided that they would  make this a real vacation by not wearing anything that would identify them  as clergy.  As soon as the plane landed, they headed for a store and bought  some really outrageous shorts and shirts, sandals, sunglasses, etc.  The  next morning, they went to the beach, dressed in their "tourist" garb and  were sitting on beach chairs, enjoying a drink, the sunshine and the  scenery when a drop dead gorgeous blonde in a tiny bikini came walking  straight toward them.  They couldn't help but stare and when she passed  them she turned to them, smiled and said, "Good morning, Father; Good  morning, Father," nodding and addressing each of them individually, then
 passed on by.  They were both stunned--how in the world did she recognize  them as priests?

 The next day they went back to the store, bought even more outrageous  outfits--these were so loud, you could hear them before you even saw  them--and again they settled on the beach in their chairs to enjoy the
 sunshine, etc.  After a while, the same gorgeous blonde, wearing a string  bikini this time, came walking toward them again.  (They were glad they had  sunglasses, because their eyes were about to pop out of their  heads).  Again, she approached them and greeted them individually: "Good  morning, Father; Good morning, Father," and started to walk away.  One of  the priests couldn't stand it and said, "Just a minute young lady.  Yes we are priests, and proud of it, but I have to know, how in the world did YOU  know?"

 "Oh Father, don't you recognize me? I'm Sister Kathryn!"
