Sisters of St. Francis

I found this to be quite funny! Do you agree?

Sisters of St. Francis

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 a figment of his imagination and drives on
without 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 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", the nun answers. "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 another nun in a long habit,
holding a tin cup answers the door.  This nun instructs,
"Please place $100 in the cup, then go through the large
wooden door at the end of this hallway."

He gets $100 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.
  SERVES YOU RIGHT,
  YOU SINNER.
