A priest decides to pay a visit to a nearby convent.
The convent is in a run-down neighborhood, and as
the priest walks down the street several prostitutes
approach and proposition him.
"Twenty bucks a trick!"
These solicitations embarass the priest who lowers
his head and hurries on until he gets to the convent.
Once inside he displays his naivete by asking the
Mother Superior, "What is a trick?"
She answers, "Twenty bucks -- just like on the outside!"
