Pork and sex
A priest and a rabbi were traveling on a plane.
After a while the priest turned to the rabbi and asked, "Is it still a requirement of your faith that you not eat pork?"
The rabbi responded, "Yes, that is still one of our beliefs."
The priest then asked, "Have you ever eaten pork?"
To which the rabbi replied, "Yes, on one occasion I did succumb and tasted pork."
The priest nodded in understanding and went back to his reading.
After a while the rabbi asked the priest, "Father, is it still a requirement of your faith that you remain celibate?"
The priest replied, "Yes that is still very much a part of our faith."
The rabbi then asked him, "Father, have you ever fallen to the temptation of the flesh?"
The priest replied, "Yes, rabbi, on one occasion I was weak and broke with my faith."
The rabbi nodded understandingly for a moment and then said, "A lot better than pork isn't it?"
