Each dog ... to show a trick. One dog ... to pretend that it could count, another dog ... to ride a bicycle. At the end of the performance they showed a dog, Fray by name, who could play the piano. Fray was the chief attraction, and before it began its trick, the manager always stood up and said: quot;And now, boys and girls, you ... to be very quiet. Fray, our greatest artist ... to play the pianoquot;. The dog sat on a chair, put its paws on the piano and seemed to play it. One day during the performance Fray started to play the piano as usual. Suddenly one of the boys shouted loudly: quot;Ratsquot;. Immediately quot;the artistquot; jumped off the chair and rushed in the direction of the cry. And here everybody burst out laughing - the piano continued to play.
