A priest is moved from his parish in the country to the Bronx in New York.    He goes walking daily in the evening to know his neighborhood.    He gets annoyed by all the hookers in the street corners who come to him and whisper $20 for a blow job.    He has no idea what a blow job is.    Finally, he decides to find it out.     When he returns to the chapel, he confronts one of the nuns and asks her, "excuse me sister, what is a blow job".    The nun says '$20 for the blow job, same as anywhere in the neighborhood".
