A fellow got up one morning and decided he no longer was going to shave himself, he was instead going to the barber for his morning shave.
The town barber also happened to be the local pastor in town. When the guy walked into the barber shop the barber/pastor was not there, he was out on a pastoral call but his wife Grace was in the shop.
The man said to Grace, "I want a shave." Grace told him to climb up in the chair and she gave him a shave. When Grace was finished he asked her how much for the shave and Grace said, "Twenty dollars."
"Twenty dollars, that seems a little steep," the guy replied.
Grace said: "That's my charge."
So the guy gave her $20 bill and went on his way. The next morning when he got up he went to the mirror and looked and his face was as smooth as when he was shaved the day before. He checked the following the day, same thing, a week went by, two weeks and his face stayed as smooth as a baby's face.
Finally after the third week he stopped back in the barber shop and Grace happened to be there. The guy said to her: "Grace, I can't believe I still don't need another shave. You did some kind of magnificent job."
And Grace replied, "Well, you have been shaved by Grace and once shaved always shaved!"
