A Trip by Plane
An American farmer wanted to make an air trip. There was an airport close to his farm. So one morning he came there to ask if he could make an air trip.
"You see," he said to one of the pilots, "I have never flown before, but I would like to." The pilot told him that the price of the trip was 10 dollars for a ten-minute trip. "Oh, it's a dollar a minute," the farmer said. "Can't you reduce the price?" The pilot thought for a minute and then said, "I won't take any money if you don't say a word during the whole trip." The farmer agreed.
"By the way," said the pilot, "you may take your wife too." The farmer was happy.
The next day at three o'clock the farmer and his wife arrived at the airport. Soon they were up in the air. The plane flew at a high speed, it went up and down very quickly, but since the passengers didn't say a word.
"You are brave people," said the pilot. "I thought you would be afraid to fly."
