I love this joke ...
A guy was driving home from a long business trip and he noticed a sign on the side of the road that said "Sisters of Mary Brothel - 5 Miles". He thought to himself "That has to be a joke ...". Then a little bit later he sees a another sign saying "Sisters of Mary Brothel - 2 Miles". He thought ... "Oh my goodness, could it be? I've always had this fantasy."
Well he finally sees the entrance and goes in ... He walks up to the door and knocks and a pretty nun answers the door. He asks "Is this really 'Sisters of Mary Brothel'?". She says "You have the right place ...".
He asks her how much ... and she says "It's free ... but we only ask that you put a donation in the offering plate." He thinks "Alright ... this is awesome!". Well he puts $60.00 in the plate ... and walks through the door ... and the door shuts behind him. He looks around only to realize he's in a alley and there is a sign in front of him that says "You've just been f**ked by the Sisters of Mary."
