@George,
A man was driving through Nevada, on his way from Las Vegas to Reno, when he saw a big roadside sign that said, "Sisters of Mercy. For a good time, come see us!" There was also a picture of a very good looking young woman wearing what appeared to be a nun's habit.
Intrigued, the fellow turned into a side road when he saw an arrow and another sign, reading "Sisters of Mercy. Drive right up."
He came to wat appeared to be a very conventional convent house with a large parking lot, parked his vehicle and went up to the front entrance. At his knock, the door was opened by an austere looking woman, dressed pretty much as you'd expect a Mother Superior or Abess to to be dressed. "Uh, I saw your signs," the man stammered. "I hope I'm in the right place. I'd sure like to get fixed up."
The abess smiled. "No problem," she said. "It will cost you $200, cash."
A few dollars richer from a recent stroke of good luch in Vegas, the man pulled out a wallet and handed over two C-notes. The 'Mother Superior' said: "Thank you. Now just go down the hall here and take the last door on your right. Go right in, don't even knock."
The fellow did as he had been told. He opened the door, stepped through, and the door closed and locked shut behind him. He looked around and realized he was back in the parking lot. Then he noticed the sign on the door he had just come through. It said
THANK YOU, BROTHER
YOU HAVE JUST BEEN SCREWED BY
THE SISTERS OF MERCY
