A man is out driving along a back country highway and passes a sign which reads:
SISTERS OF MERCY - HOUSE OF PROSTITUTION -10 MILES
He thinks that it was a figment of his imagination and drives on.
Soon, he sees another sign that says: SISTERS OF MERCY - HOUSE OF PROSTITUTION - 5 MILES
Realizing these signs are for real, he drives a little farther on and sure enough, there is a third sign: SISTERS OF MERCY - HOUSE OF PROSTITUTION -NEXT RIGHT.
His curiosity gets the best of him and he pulls into the driveway. On the far side of the parking lot he sees a somber stone building with a sign on the door that reads: SISTERS OF MERCY - HOUSE OF PROSTITUTION.
He climbs the steps and rings the bell. The door is answered by a nun in a long black habit who asks, 'What may we do for you my son?'
'I saw your signs posted while I was driving along the highway and so I was interested in possibly doing some business,' he answers.
'Very well, my son. Please follow me,' she says.
He is led through many winding passages, and so he is very disoriented.
The nun stops in front of a closed door and tells the man, 'Please, knock on this door' and leaves.
The man does as he is told. This door is opened by another nun in a long black habit, holding a tin cup.
This nun instructs: 'Please place $50.00 in the cup, then go through the large wooden door at the end of this hallway and close the door behind you.'
He places the money in this nun's tin cup. He trots eagerly down the hallway and slips through the door, pulling it shut.
As the door locks behind him, he finds himself back out in the parking lot, and facing another small sign:
'Go in Peace. You have just been screwed by the Sisters of Mercy.
