Twenty dollars, same as in town.
The punchline of an old joke.
The aging head of a secluded Monastary decides he will take a walk into the nearby town for the first time in 30 years. As he's walking down the street he passes a hooker on a corner who says "Hey twenty dollars for a quicky". Confused, he walks past another corner and another hooker says "Hey padre, twenty dollars for a quicky". He has no idea whats going on, so he returns to the monastary and calls the Mother Superior to his office and asks her "Whats a quicky?" She replies "Twenty dollars, same as in town".
