The children and grand children of an elderly Jewish woman decided to send grandma on a cruise.
Grandma boarded the ship and showed her ticket to the purser.
He looked at it and said, “Oh, I see you have U.D.”
She replied, “U.D.- Vos is U.D?
He said, “U.D. is Upper Deck.”
She then went to the upper deck and showed her ticket to the purser there and he said, “I see, that in addition to U.D., you also have O.C.”
“Grandma replied, “O.C.? Vos is O.C?”
The purser said, “O.C. is Outside Cabin.”
Grandma, needless to say, was delighted.
She then showed her ticket to the cabin boy, and he said, “Oh, I see that you also have B.I.B.”
“B.I.B.? Vos is B.I.B.?” asked grandma.
The cabin boy answered, “B.I.B. is Breakfast In Bed.”
“Oh!” she said; Mine children and grandchildren are vonderful.”
Well, the next morning, bright and early, the staff came right into her room with trays of food for her breakfast in bed, and she said, “F.C.U.K.”
Shocked, they said, “F.C.U.K? What do you mean F.C.U.K?”
To which she replied, “F. C. U.K…………Foist Could U Knock!”
