Two clergy persons are on an airplane, a Catholic priest and a Mormon bishop. After a while, the priest turns to the bishop and asks, "Is it still a requirement of your faith that you are not to drink coffee?" The Mormon bishop responds, "Yes that is still one of our beliefs." The Catholic priest then asks, "Have you ever had a cup of coffee"? "Yes," says the Mormon bishop, "I have to admit on one occasion, I did succumb to temptation and tried a cup of coffee." The Catholic priest nods in understanding and goes on with his reading.

A while later, the Mormon bishop speaks up and asks, "Father, is it still a requirement of your church that you remain celibate?" The Catholic priest replies, "Yes, that is still one of our vows." The Mormon bishop then asks, "Father, have you ever fallen to the temptations of the flesh?" The Catholic priest replied, "Yes, Bishop, on one occasion, I was weak and broke my vow." The Mormon bishop nodded understandingly for a moment. A few minutes later he smiled, looked at the Catholic priest and then said, "A lot better than coffee, isn't it?"
