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 it 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?"
