A man had been driving for many days and was exhausted and lonely. As he was driving down the highway, he noticed a sign that said, "Sisters of Mercy House of Prostitution, 10 miles". He figured it was just a figment of his imagination, he ignored it.
5 miles later, he saw another sign that said, "Sisters of Mercy House of Prostitution, 5 miles". He now knew it was real. So he continued driving and looking for another sign. 5 miles later, he saw a sign that said, "Sisters of Mercy House of Prostitution, next left".
So at the next left turn, he turned left. He saw a big building with a sign above the door that said, "Sisters of Mercy House of Prostitution".
He parked his car and went inside. He saw a nun that said, "Go down the hall, and go inside the big wooden door.
So he did as the nun said.
Inside the door there was another nun, that said, "Put $150 dollars in this cup, go down this hallway and go through the double wooden doors.
The man did as this nun said.
When he went out the two wooden doors, he realized that he was back in the parking lot, facing a sign that said
"YOU HAVE NOW BEEN SCREWED BY THE SISTERS OF MERCY!!"
