The children and grandchildren 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.? Voos 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.

He said, “I see that in addition to U.D., you also have O.C.”

Grandma replied, “O.C.? Voos 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.”

“Voos is B.I.B.?” asked Grandma.

The cabin boy answered, “B.I.B. is Breakfast In Bed.”

“Oh!!!” she said, “My children and grandchildren are wonderful.”

Well, the next morning, bright and early, the staff came right into her room with trays of food for her breakfast in bed.

She said, “F.U.C.K”

Shocked, they said, “F.U.C.K? What do you mean F.U.C.K.?”

To which she replied, “Yes, F.U.C.K…. First U Could Knock!”
