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, "Iwon'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."

“Well,” said the farmer, “I am glad, Iwill not have to pay for the trip,
as I didn’t have to say a word, but I wanted to speak to you when my wife fell
out of the plane”
