Mark Twain was famous in his days as a public speaker. In his public speeches he always liked to tell funny stories. He also liked to listen to funny stories and play jokes on his friends.

One day one of his friends lost his wallet and asked Mark Twain to pay his train fare （车费）for him.

“But I don’t have enough money to pay both your fare and mine, ”Mark Twain said. The friend didn’t know what to do.

“We can do this, ”said Mark Twain. “We can get on the train and when the conductor(列车员) comes to check the tickets，you can hide(藏) under my seat. ”

Later, however, when the conductor came to check the tickets, Mark Twain gave him two tickets－one for his friend and one for himself . Then he explained in a loud voice. “My friend here is a strange man. When he travels on a train, he doesn’t like to sit on the seat. He prefers （宁愿）to lie on the floor under the seat. ”Of course everybody in the train looked at the poor friend and laughed at him loudly.
