A person from Scotland to London, would like to visit an old friend, but forgot his address, then to my father sent a telegram: "you know Tom's address? So, on the same day, he received an urgent call back: "know." There are three resorts in New York. They have a high-rise hotelbooked a suite of forty-fifth layer. One night, the building elevator failure, the waiter arranged for them to spend the night in the hall. They discuss, decided to walk back to the room, and agreed to make jokes, singing and telling stories, the floor to reduce fatigue. Jokes, sing songs, very not easy to climb to the thirty-fourth floor, we all feel be dead beat. "Well, Peter,you tell a humorous story, Peter said:" the story is not long, but extremely sad: I left the room key in the hall."
