Two priests are making their way to a remote monastery by foot. To get there,
however, they have to go through the town and the town is full of hookers.
The first they pass, flashes her thighs and says "Want some fun, just 20
bucks for the night".
Anyway, the priests are shocked and hurry on their
way.
This goes on about three more times.
The weather starts getting bad and they are nowhere near the monastery yet. A
big storm is brewing, lightning flashes etc. the priests are very lucky to find
a nunnery on their way.
They go in, explain their situation to the Mother Superior and ask if there
is room to sleep.
Then they ask "How much for the night?"
To which she answers "20 bucks, same as in town".
