Twain, a famous American writer, was travelling in France. Once he
was going by train to Dijon. That afternoon he was very tired and
wanted to sleep. He therefore asked the conductor to wake him up when
they came to Dijon. But first he explained he was a very heavy
sleeper. “I’ll probably protest loudly when you try to wake me
up,” he said to the conductor. “But do not take any notice, just
put me off the train anyway.”
When Mark Twain woke up, the train was already in Paris. The angry writer ran up to the conductor and said, “I’ve never been so angry in all my life.”
The conductor looked at him calmly. “You are not half so angry as the American whom I put off the train at Dijon,” he said.
