THE SISTERS OF MERCY

A man is driving down a deserted stretch of highway in
Nevada when he notices a sign out of the corner of his eye. 
It reads: SISTERS OF MERCY HOUSE OF PROSTITUTION - 10 MILES. 
He thinks it was just a figment of his imagination and
drives on without a second thought.  Soon, he sees another
sign which says: SISTERS OF MERCY HOUSE OF PROSTITUTION - 5
MILES.  He realizes that these signs are for real.

When he drives past a third sign saying SISTERS OF MERCY
HOUSE OF PROSTITUTION - NEXT RIGHT, his curiosity gets the
best of him and he pulls into the drive.  On the far side of
the parking lot is a somber stone building with a small sign
next to the door reading: SISTERS OF MERCY.  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?"  He answers, "I saw your signs along the highway, and
was interested in possibly doing business."  "Very well, my
son. Please follow me."  He is led through many winding
passages and is soon quite disoriented.  The nun stops at a
closed door and tells the man, "Please knock on this
door..."

He does as he is told, and this door is answered by another
nun in a long habit and holding a tin cup. This nun says,
"Please place $50 in the cup, then go through the large
wooden door at the end of this hallway."  He gets $50 out of
his wallet and places it in the second nun's cup.  He trots
eagerly down the hall and slips through the door, pulling it
shut behind him...

As the door locks behind him, he finds himself back in the
parking lot, facing another small sign: GO IN PEACE. YOU
HAVE JUST BEEN SCREWED BY THE SISTERS OF MERCY.
