Two priests decided to go on a Hawaiian vacation.
They were determined to 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, shirts, sandals, sunglasses, etc.
The next morning, they went to the beach, dressed in their "tourist" garb. They were sitting on beach chairs, enjoying a drink, the sunshine and the scenery when a "drop-dead-gorgeous," topless blonde in a thong bikini came walking toward them. Of course they couldn't help but stare.
As the blonde passed, she smiled and said, "Good morning, Father, and you too Father," to them, and went on her way.
They were stunned.... how in the world could she tell they were priests?
The next day, they went back to the store and bought more outfits. These were so loud you could HEAR them before you even saw them. Once again, the two priests (incognito) settled in their chairs on the beach to enjoy the sunshine.
After a while, the same gorgeous, topless blonde came walking by. Once again she nodded at them, smiled pleasantly, said "Good morning, Fathers," and started to walk away.
One of the priests couldn't stand it any longer and said. "Just a minute, young lady."
Yes?" she replied.
We ARE priests, and proud of it, but I have to know one thing. How in the world did you know we're priests, dressed as we are?"
Father," she whispered, "it's me, Sister Mary Francis."
