A man is driving down a deserted stretch of highway one night 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 is a figment of his imagination and continues driving.
Soon, he sees another sign, which reads: "Sisters of St. Francis, House of Prostitution, 5 Miles". He begins to think that the signs are for real.
Then he drives past a third sign, reading: "Sisters of St. Francis, House of Prostitution, Next Right". His curiosity gets the best of him so he takes the next right and ends up in the parking lot of a stone building. A sign next to the door reads: "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?"
"I saw your signs along the highway and was interested in possibly doing business," he says.
"Very well, my son," the nun replies. "Please follow me." She leads him through many winding passages and he is soon a bit disoriented. The nun stops at a closed door and tells the man, "Please knock on this door."
He does and another nun, holding a tin cup answers the door. This nun quietly instructs him: "Please place $100 in the cup, then go through the large wood door at the end of this hallway," gesturing to her left.
He puts $100 in the cup then, beginning to get exicited with anticipation, trots eagerly down the hall and slips through the door, pulling it shut behind him. As he hears the door lock, he looks around and finds he is back in the parking lot, facing another small sign, that reads: "Go in peace. You have just been screwed by the Sisters of St. Francis. Serves you right, you sinner!"
