A man is driving down a deserted stretch of highway when he notices a
sign
out of the corner of his eye. It reads:

SISTERS OF ST. FRANCIS 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 ST. FRANCIS HOUSE OF PROSTITUTION 5 MILES

Suddenly, he begins to realize that these signs are for real. Then he
drives
past a third sign saying:

SISTERS OF ST. FRANCIS 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 ST. FRANCIS

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, holding a tin cup.

This nun instructs, “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 ST. FRANCIS
