A priest and a rabbi were sitting next to each other on an airplane. 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 to temptation and tasted a ham sandwich." The priest nodded in understanding and went on with his reading. A while later, the rabbi spoke up and asked the priest, "Father, is it still a requirement of your church 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 temptations of the flesh? The priest replied, "Yes, rabbi, on one occasion I was weak and broke with my faith." The rabbi nodded understandingly and remained silent, thinking, for about five minutes. Finally, the rabbi said, "Beats a ham sandwich, doesn't it?"
